Directly known subclasses:
GcContentNormalization2

public abstract static class AdditiveCovariatesNormalization
extends ChipEffectTransform

This class represents a normalization method that corrects for GC-content effects on copy-number chip-effect estimates.

Usage

AdditiveCovariatesNormalization(dataSet=NULL, ..., target=NULL, subsetToFit="-XY",
  shift=0, onMissing=c("median", "ignore"))

Arguments

dataSet

A SnpChipEffectSet.

...

Additional arguments passed to the constructor of ChipEffectTransform.

target

(Optional) A character string or a function specifying what to normalize toward.

subsetToFit

The units from which the normalization curve should be estimated. If NULL, all are considered.

onMissing

Specifies how to normalize units for which the GC contents are unknown.

shift

An optional amount the data points should be shifted (translated).

Details

For SNPs, the normalization function is estimated based on the total chip effects, i.e. the sum of the allele signals. The normalizing is done by rescale the chip effects on the intensity scale such that the mean of the total chip effects are the same across samples for any given GC content. For allele-specific estimates, both alleles are always rescaled by the same amount. Thus, when normalizing allele-specific chip effects, the total chip effects is change, but not the relative allele signal, e.g. the allele B frequency.

Usage

AffinePlm(..., background=TRUE)

Arguments

...

Arguments passed to ProbeLevelModel.

background

If TRUE, background is estimate for each unit group, otherwise not. That is, if FALSE, a linear (proportional) model without offset is fitted, resulting in very similar results as obtained by the MbeiPlm.

Model

For a single unit group, the affine model is:

yik=a+θiϕk+εiky_{ik} = a + \theta_i \phi_k + \varepsilon_{ik}

where aa is an offset common to all probe signals, θi\theta_i are the chip effects for arrays i=1,...,Ii=1,...,I, and ϕk\phi_k are the probe affinities for probes k=1,...,Kk=1,...,K. The εik\varepsilon_{ik} are zero-mean noise with equal variance. The model is constrained such that kϕk=1\prod_k \phi_k = 1.

Note that with the additional constraint a=0a=0 (see arguments above), the above model is very similar to MbeiPlm. The differences in parameter estimates is due to difference is assumptions about the error structure, which in turn affects how the model is estimated.

For developers

If you subclass this class, please make sure to query the AffymetrixCdfFile object (see *getCdf()) whenever querying CDF information. Do not use the CDF file inferred from the chip type in CEL header, unless you really want it to be hardwired that way, otherwise you will break to possibility to override the CDF structure.

Directly known subclasses:

public static class AllelicCrosstalkCalibration
extends ProbeLevelTransform

This class represents a calibration function that transforms the probe-level signals such that the signals from the two alleles are orthogonal. The method fits and calibrates PM signals only. MM signals will not affect the model fitting and are unaffected.

Usage

AllelicCrosstalkCalibration(dataSet=NULL, ..., model=c("asis", "auto", "CRMA", "CRMAv2"),
  rescaleBy=c("auto", "groups", "all", "none"), targetAvg=c(2200, 2200),
  subsetToAvg="-XY", mergeShifts=TRUE, B=1, flavor=c("sfit", "expectile"),
  alpha=c(0.1, 0.075, 0.05, 0.03, 0.01), q=2, Q=98, lambda=2,
  pairBy=c("CDF", "sequence"))

Arguments

dataSet

An AffymetrixCelSet.

...

Arguments passed to the constructor of ProbeLevelTransform.

model

A character string for quickly specifying default parameter settings.

rescaleBy

A character string specifying what sets of cells should be rescaled towards a target average, if any. Default is to rescale all cells together. If "none", no rescaling is done.

targetAvg

The signal(s) that either the average of the sum (if one target value) or the average of each of the alleles (if two target values) should have after calibration. Only used if rescaleBy != "none".

subsetToAvg

The indices of the cells (taken as the intersect of existing indices) used to calculate average in order to rescale to the target average. If NULL, all probes are considered.

mergeShifts

If TRUE, the shift of the probe sequence relative to the SNP position is ignored, otherwise not.

B

An integer specifying by how many nucleotides the allelic groups should be stratified by. If zero, all SNPs are put in one group.

flavor

A character string specifying what algorithm is used to fit the crosstalk calibration.

alpha, q, Q, lambda

Model fitting parameters.

pairBy

A character string specifying how allele probe pairs are identified.

What probe signals are updated?

Calibration for crosstalk between allele signals applies by definition only SNP units. Furthermore, it is only SNP units with two or four unit groups that are calibrated. For instance, in at least on custom SNP CDFs we know of, there is a small number of SNP units that have six groups. Currently these units are not calibrated (at all). It is only PM probes that will be calibrated. Note that, non-calibrated signals will be saved in the output files.

What probe signals are used to fit model?

All PM probe pairs are used to fit the crosstalk model. In the second step where signals are rescaled to a target average, it is possible to specify the set of cells that should be included when estimating the target average.

Important about rescaling towards target average

Rescaling each allele-pair group (e.g. AC, AG, AT, CG, CT, GC) towards a target average (rescaleBy="groups") must not be used for multi-enzyme chip types, e.g. GenomeWideSNP_6. If still done, due to confounded effects of non-perfect enzyme mixtures etc, there will be a significant bias between raw CNs for SNPs and CN probes. Instead, for such chip types all probe signals should be rescale together towards the target average (rescaleBy="all").

Model

For a single unit group, the averaging PLM of K probes is:

yik=θi+εiky_{ik} = \theta_i + \varepsilon_{ik}

where θi\theta_i are the chip effects for arrays i=1,...,Ii=1,...,I. The εik\varepsilon_{ik} are zero-mean noise with equal variance.

Different flavors of model fitting

The above model can be fitted in two ways, either robustly or non-robustly. Use argument flavor="mean" to fit the model non-robustly, i.e.

θ^i=1/Kkyik\hat{\theta}_{i} = 1/K \sum_k y_{ik}

.

Use argument flavor="median" to fit the model robustly, i.e.

θ^i=mediankyik\hat{\theta}_{i} = median_k y_{ik}

.

Missing values are always excluded.

Interface
~~|
~~+--SnpPlm
~~~~~~~|
~~~~~~~+--CnPlm

Directly known subclasses:
AffineCnPlm, AvgCnPlm, HetLogAddCnPlm, MbeiCnPlm, RmaCnPlm

public class CnPlm
extends SnpPlm

This support class represents a SnpPlm specially designed for copy-number analysis.

Usage

CnPlm(...)

Arguments

...

Arguments passed to SnpPlm.

Details

Models implementing this copy-number PLM, provides either allele-specific or total copy-number estimates. For allele-specific CNs the underlying SnpPlm model is fitted as is, i.e. for each allele separately with or without the strands first being merged.

For total CNs the probe signals for the two alleles are combined (=summed; not averaged) on the intensity scale before fitting underlying SnpPlm model, again with or without the strands first being merged.

Methods

Methods:

getCellIndices -
getChipEffectSet -
getCombineAlleles -
getProbeAffinityFile -
setCombineAlleles -

Methods inherited from SnpPlm:
getCellIndices, getChipEffectSet, getMergeStrands, getParameters, getProbeAffinityFile, setMergeStrands

Methods inherited from Interface:
extend, print, uses

Requirements

Classes inheriting from this Interface must provide the following fields, in addition to the ones according to SnpPlm:

combineAlleles

A logical indicating if total or allele-specific copy numbers should be estimated according to the above averaging.

This class represents dChip genome information files, which typically contains information about chromosomal locations of the units.

Usage

DChipGenomeInformation(...)

Arguments

...

Arguments passed to GenomeInformation.

Details

The dChip genome information files for various chip types can be downloaded from https://sites.google.com/site/dchipsoft/. Put each file in a directory named identically as the corresponding chip type under the annotations/ directory, e.g. annotations/Mapping50K_Hind240/50k hind genome info AfAm june 05 hg17.xls. Note that dChip changes the filename and file format slightly between chip types, but currently the *byChipType() basically searches for files with names consisting of "genome info" or "genome_info". At least for the most common chip types, there is no need to rename the files in order for this class to recognize them.

Fields and Methods

Directly known subclasses:

public abstract static class DChipSnpInformation
extends SnpInformation

This class represents dChip genome information files, which typically contains information on nucleotide sequences and fragment lengths of the units.

Usage

DChipSnpInformation(...)

Arguments

...

Arguments passed to SnpInformation.

Details

The dChip SNP information files for various chip types can be downloaded from https://sites.google.com/site/dchipsoft/. Put each file in a directory named identically as the corresponding chip type under the annotations/ directory, e.g. annotations/Mapping50K_Hind240/50k hind snp info AfAm june 05 hg17.xls. Note that dChip changes the filename and file format slightly between chip types, but currently the *byChipType() basically searches for files with names consisting of "snp info" or "snp_info". At least for the most common chip types, there is no need to rename the files in order for this class to recognize them.

Estimation and assessment of raw copy numbers at the single locus level (CRMA v1)

Description

Estimation and assessment of raw copy numbers at the single locus level (CRMA v1) based on [1]. The algorithm is processed in bounded memory, meaning virtually any number of arrays can be analyzed on also very limited computer systems.

Usage

## S3 method for class 'AffymetrixCelSet'
doCRMAv1(csR, shift=+300, combineAlleles=TRUE, lengthRange=NULL, arrays=NULL, drop=TRUE,
  verbose=FALSE, ...)
  ## Default S3 method:
doCRMAv1(dataSet, ..., verbose=FALSE)
  ## Default S3 method:
doASCRMAv1(...)

Arguments

csR, dataSet

An AffymetrixCelSet (or the name of an AffymetrixCelSet).

shift

An tuning parameter specifying how much to shift the probe signals before probe summarization.

combineAlleles

A logical specifying whether allele probe pairs should be summed before modeling or not.

lengthRange

An optional numeric vector of length two passed to FragmentLengthNormalization.

arrays

A integer vector specifying the subset of arrays to process. If NULL, all arrays are considered.

drop

If TRUE, the summaries are returned, otherwise a named list of all intermediate and final results.

verbose

See Verbose.

...

Additional arguments used to set up AffymetrixCelSet (when argument dataSet is specified).

Value

Returns a named list, iff drop == FALSE, otherwise only ChipEffectSet object.

Allele-specific or only total-SNP signals

If you wish to obtain allele-specific estimates for SNPs, which are needed to call genotypes or infer parent-specific copy numbers, then use argument combineAlleles=FALSE. Total copy number signals are still available. If you know for certain that you will not use allele-specific estimates, you will get slightly less noisy signals (very small difference) if you use combineAlleles=TRUE.

doASCRMAv1(...) is a wrapper for doCRMAv1(..., combineAlleles=FALSE).

If TRUE, the summaries are returned, otherwise a named list of all intermediate and final results.

verbose

See Verbose.

...

Additional arguments used to set up AffymetrixCelSet (when argument dataSet is specified).

Value

Returns a named list, iff drop == FALSE, otherwise only ChipEffectSet object.

Allele-specific or only total-SNP signals

If you wish to obtain allele-specific estimates for SNPs, which are needed to call genotypes or infer parent-specific copy numbers, then use argument combineAlleles=FALSE.

Finding Isoforms using Robust Multichip Analysis (FIRMA)

Description

Finding Isoforms using Robust Multichip Analysis (FIRMA) based on [1].

Usage

## S3 method for class 'AffymetrixCelSet'
doFIRMA(csR, ..., flavor=c("v1b", "v1a"), drop=TRUE, verbose=FALSE)
  ## Default S3 method:
doFIRMA(dataSet, ..., verbose=FALSE)

Arguments

csR, dataSet

An AffymetrixCelSet (or the name of an AffymetrixCelSet).

...

Additional arguments passed to FirmaModel, and to set up AffymetrixCelSet (when argument dataSet is specified).

flavor

A character string specifying the flavor of FIRMA to use.

drop

If TRUE, the FIRMA scores are returned, otherwise a named list of all intermediate and final results.

verbose

See Verbose.

Value

Returns a named list, iff drop == FALSE, otherwise only FirmaSet object (containing the FIRMA scores).

Using a custom exon-by-transcript CDF

It is strongly recommended to use a custom CDF, e.g. "core", "extended" or "full" [1]. To use a custom CDF, set it before calling this method, i.e. setCdf(csR, cdf). Do not set the standard "non-supported" Affymetrix CDF (see also Section 'Flavors').

Flavors

If flavor == "v1b" (default), then the standard "non-supported" Affymetrix CDF is used for background correction and the quantile normalization steps, and the custom CDF is used for the probe summarization and everything that follows. The advantage of this flavor is that those two first preprocessing steps will remain the same if one later changes to a different custom CDF.

If flavor == "v1a", then the custom CDF is used throughout all steps of FIRMA, which means that if one changes the custom CDF all steps will be redone.

Directly known subclasses:

public static class FragmentLengthNormalization
extends ChipEffectTransform

This class represents a normalization method that corrects for PCR fragment length effects on copy-number chip-effect estimates.

Usage

FragmentLengthNormalization(dataSet=NULL, ..., target=targetFunctions, subsetToFit="-XY",
  lengthRange=NULL, onMissing=c("median", "ignore"), shift=0, targetFunctions=NULL)

Arguments

dataSet

A SnpChipEffectSet.

...

Additional arguments passed to the constructor of ChipEffectTransform.

target

(Optional) A character string or a list of functions specifying what to normalize toward. For each enzyme there is one target function to which all arrays should be normalized to.

subsetToFit

The units from which the normalization curve should be estimated. If NULL, all are considered.

lengthRange

If given, a numeric vector of length 2 specifying the range of fragment lengths considered. All fragments with lengths outside this range are treated as if they were missing.

onMissing

Specifies how to normalize units for which the fragment lengths are unknown.

shift

An optional amount the data points should be shifted (translated).

targetFunctions

Deprecated.

Details

For SNPs, the normalization function is estimated based on the total chip effects, i.e. the sum of the allele signals. The normalizing is done by rescale the chip effects on the intensity scale such that the mean of the total chip effects are the same across samples for any given fragment length. For allele-specific estimates, both alleles are always rescaled by the same amount. Thus, when normalizing allele-specific chip effects, the total chip effects is change, but not the relative allele signal, e.g. the allele B frequency.

Arguments

...

Arguments passed to the constructor of ProbeLevelTransform.

indicesNegativeControl

Locations of any negative control probes (e.g., the anti-genomic controls on the human exon array). If NULL and type == "affinities", then all non-PM probes are used as the negative controls.

affinities

A numeric vector of probe affinities, usually as calculated by computeAffinities() of the AffymetrixCdfFile class.

type

Type (flavor) of background correction, which can be either "fullmodel" (uses MMs; requires that the chip type has PM/MM pairs) or "affinities" (uses probe sequence only).

gsbAdjust

If TRUE, adjustment for specific binding is done, otherwise not.

opticalAdjust

If TRUE, correction for optical effect is done first, utilizing OpticalBackgroundCorrection.

gsbParameters

Additional argument passed to the internal bgAdjustGcrma() method.

seed

Robust Multichip Analysis (RMA) reproducing the affy package

Description

Robust Multichip Analysis (RMA) reproducing the affy package as far as possible. The RMA method is described in [1].

The algorithm is processed in bounded memory, meaning a very large number of arrays can be analyzed on also very limited computer systems. The only limitation is the amount of memory required to load the final chip-effect estimates into memory (as a ExpressionSet).

Usage

## S3 method for class 'AffymetrixCelSet'
justRMA(csR, flavor=c("oligo", "affyPLM"), ..., verbose=FALSE)
  ## Default S3 method:
justRMA(...)

Arguments

csR

An AffymetrixCelSet.

flavor

A character string specifying the estimators used in the RMA summarization step.

...

Additional arguments passed to doRMA() used internally.

verbose

See Verbose.

Value

Returns an annotated ExpressionSet.

Reproducibility of affy

This implementation of the RMA method reproduces justRMA in affy package quite well. It does so by still using a constant memory profile, i.e. it is possible to use this implementation to run RMA on a much large data set than what is possible with affy. At least 20-50 times more samples should be doable, if not more.

This class represents the various "background" correction methods implemented in the limma package.

Usage

LimmaBackgroundCorrection(..., args=NULL, addJitter=FALSE, jitterSd=0.2, seed=6022007)

Arguments

...

Arguments passed to the constructor of BackgroundCorrection.

args

A list of additional arguments passed to the correction algorithm.

addJitter

If TRUE, Zero-mean gaussian noise is added to the signals before being background corrected.

jitterSd

Standard deviation of the jitter noise added.

seed

An (optional) integer specifying a temporary random seed to be used for generating the (optional) jitter. The random seed is set to its original state when done. If NULL, it is not set.

Jitter noise

The fitting algorithm of the normal+exponential background correction model may not converge if there too many small and discrete signals. To overcome this problem, a small amount of noise may be added to the signals before fitting the model. This is an ad hoc solution that seems to work. However, adding Gaussian noise may generate non-positive signals.

Requirements

This class requires that an aroma probe sequence file is available for the chip type.

Memory usage

The model fitting methods of this class are bounded in memory. This is done by first building up the normal equations incrementally in chunks of cells. The generation of normal equations is otherwise the step that consumes the most memory. When the normal equations are available, the solve() method is used to solve the equations. Note that this algorithm is still exact.

Model

For a single unit group, the multiplicative model is:

yik=θiϕk+εiky_{ik} = \theta_i \phi_k + \varepsilon_{ik}

where θi\theta_i are the chip effects for arrays i=1,...,Ii=1,...,I, and ϕk\phi_k are the probe affinities for probes k=1,...,Kk=1,...,K. The εik\varepsilon_{ik} are zero-mean noise with equal variance. To make to parameters identifiable, the constraint kϕk=1\prod_k \phi_k = 1 is added.

File format

The idea behind this class is store data fields which by nature have one value per probe (per field) in CEL files. A perfect example is to store probe-affinity estimates and their standard deviations. There is one probe affinity per probe so the structure of a CEL file (and its coupled CDF file) is well suited to read/write such information.

Consider a unit group with L probes. A CEL file stores intensities (L floats), stdvs (L floats), and pixels (L integers). Thus, for each probe l=1,...,L, a (float, float, integer) tuple is stored. We can use this for any information we want. If we want a slightly different structure, we can choose to encode/decode our structure/information to fit the structure of the CEL file. This abstract class provides transparent methods for encoding and decoding such information through methods encodeUnitGroup() and decodeUnitGroup(). By subclassing you can implement different types of data structures.

public abstract static class ProbeLevelModel
extends MultiArrayUnitModel

This abstract class represents a probe-level model (PLM) as defined by the affyPLM package: "A [...] PLM is a model that is fit to probe-intensity data. More specifically, it is where we fit a model with probe level and chip level parameters on a probeset by probeset basis", where the more general case for a probeset is a unit group in Affymetrix CDF terms.

Usage

ProbeLevelModel(..., standardize=TRUE)

Arguments

...

Arguments passed to MultiArrayUnitModel.

standardize

If TRUE, chip-effect and probe-affinity estimates are rescaled such that the product of the probe affinities is one.

Details

In order to minimize the risk for mistakes, but also to be able compare results from different PLMs, all PLM subclasses must meet the following criteria:

  1. All parameter estimates must be (stored and returned) on the intensity scale, e.g. log-additive models such as RmaPlm have to transform the parameters on the log-scale to the intensity scale.

  2. The probe-affinity estimates ϕk\phi_k for a unit group must be constrained such that kϕk=1\prod_k \phi_k = 1, or equivalently if ϕk>0\phi_k > 0,klog(ϕk)=0\sum_k \log(\phi_k) = 0.

Note that the above probe-affinity constraint guarantees that the estimated chip effects across models are on the same scale.

Directly known subclasses:

public static class RmaBackgroundCorrection
extends BackgroundCorrection

This class represents the RMA background adjustment function.

Usage

RmaBackgroundCorrection(..., addJitter=FALSE, jitterSd=0.2, seed=6022007)

Arguments

...

Arguments passed to the constructor of BackgroundCorrection.

addJitter

If TRUE, Zero-mean gaussian noise is added to the signals before being background corrected.

jitterSd

Standard deviation of the jitter noise added.

seed

An (optional) integer specifying a temporary random seed to be used for generating the (optional) jitter. The random seed is set to its original state when done. If NULL, it is not set.

Details

Internally bg.adjust is used to background correct the probe signals. The default is to background correct PM signals only.

Jitter noise

The fitting algorithm of the RMA background correction model may not converge if there too many small and discrete signals. To overcome this problem, a small amount of noise may be added to the signals before fitting the model. This is an ad hoc solution that seems to work. However, add Gaussian noise may generate non-positive signals.

Arguments

Model

For a single unit group, the log-additive model of RMA is:

log2(yik)=βi+αk+εiklog_2(y_{ik}) = \beta_i + \alpha_k + \varepsilon_{ik}

where βi\beta_i are the chip effects for arrays i=1,...,Ii=1,...,I, and αk\alpha_k are the probe affinities for probes k=1,...,Kk=1,...,K. The εik\varepsilon_{ik} are zero-mean noise with equal variance. The model is constrained such that kαk=0\sum_k{\alpha_k} = 0.

Note that all PLM classes must return parameters on the intensity scale. For this class that means that θi=2iβ\theta_i = 2^\beta_i and ϕk=2kα\phi_k = 2^\alpha_k are returned.

Different flavors of model fitting

There are a few differ algorithms available for fitting the same probe-level model. The default and recommended method (flavor="affyPLM") uses the implementation in the preprocessCore package which fits the model parameters robustly using an M-estimator (the method used to be in affyPLM).

Alternatively, other model-fitting algorithms are available. The algorithm (flavor="oligo") used by the oligo package, which originates from the affy packages, fits the model using median polish, which is a non-robust estimator. Note that this algorithm does not constraint the probe-effect parameters to multiply to one on the intensity scale. Since the internal function does not return these estimates, we can neither rescale them.
