\name{minfinews} \title{Minfi News} \encoding{UTF-8} \section{Version 1.15}{ \itemize{ \item Adding testing for preprocessNoob, preprocessFunnorm. \item Fxing some verbose output of preprocessNoob. \item Adding non-exported function .digestVector for testing. } } \section{Version 1.13}{ \itemize{ \item read.450k.exp has support for argument base when targets is supplied. Thanks to Brent Pedersen for noticing this and providing an initial fix. \item changed the default behaviour of read.450k.exp. If called using a targets argument created by read.450k.sheet, you should not also give it a base argument (which was always superfluous). \item Some NAMESPACE imports fixes. \item getGenomicRatioSetFromGEO added to read directly from GEO and create a GenomicsRatioSet. Thanks Tim Triche for writing the original function. \item makeGenomicRatioSetFromMatrix added. This function turns a matrix into a GenomicRatioSet. The 450K feature IDs need to be supplied or in the rownames of the matrix. \item makeGenomicRatioSetFromMatrix added to convert matrices to GenomicRatioSets. This can be useful for reading in files with beta values and turning into object that can be directly passed to bumphunter and blockFinder. \item readGEORawFile added to read raw intensity files provided as Supplementary Material on GEO. The files include the unmethylated and methylated signals. The new function returns a GenomicMethylSet which permits you to seamlessly apply minfi preprocessing functions. \item readTCGA is wrapper for makeGenomicRatioSetFromMatrix that reads in files in the TCGA format. The function is very specific to this format. \item Minor coding fixes including some NAMESPACE issues, missing pData<- methods, replace require() with requireNamespace(). \item cpgCollapse now works for GenomicRatioSets since it no longer attempts to summarize CN data when passed a GenomicRatioSet. \item estimateCellCounts now works on only 2 cell types. \item Various NAMESPACE fixes. \item the gaphunter function by Shan Andrews has been added. We welcome Shan as a contributing author. } } \section{Version 1.11}{ \itemize{ \item Updated CITATION. \item Added dropLociWithSnps for easy exclusion of certain methylation loci. \item Add getAnnotationObject for easy printing of contents of the annotation object. \item Changes in 1.10 imported into 1.11. \item Fixed an issue with bumphunter calling the bumphunter package in a wrong way. \item Added getOOB and getSnpBeta convenience functions for accessing the OOB probes and the SNP probes. \item read.450k.sheet now forces a column named Slide to be character. \item The NOOB background correction method is now available throguh preprocessNoob. \item One can now supply the permutations to be used in permutation analysis. This is useful for cases in which the total number of possilbe permutations is small and one wants to use them all or in cases in which one wants to assure balance, for example, between cases and controls. \item The bumphunter method now has the option to create null distributions using a bootstrap approach. \item Fixed a man page issue. \item Added GitHub URL to DESCRIPTION. \item Functional normalization now supports background correction by NOOB (see preprocessNoob); this is recommended (and the new default). } } \section{Version 1.10}{ \itemize{ \item Modified read.450k.sheet to ignore case when identifying the data header "[DATA]". This addresses an issue with sheets generated by some Illumina instruments. Reported and partial fix provided by the github user nilsigem. } } \section{Version 1.9}{ \itemize{ \item Importing the changes from 1.8 into 1.9. \item Added the withColor argument to the getProbeType function, which allows the return of "IGrn", "IRed", "II", instead of only "I", "II". \item Added asList argument to getControlAddress to return result as a list. \item Moved reshape from Depends to Imports. \item Dramatic improvement in memory usage of preprocessRaw. \item Updated CITATION, the minif paper is in press. \item Fixed bug with mapToGenome(..., mergeManifest = TRUE) reported by Dale Watkins and Allegra A. Petti . \item Fixed bug with mapToGenome(rSet) with rSet being a RatioSet with the CN set to NULL reported byAllegra A. Petti . \item Added preprocessFunnorm, a new preprocessing method. \item Improvements to the speed of getAnnotation by Martin Morgan . } } \section{Version 1.8}{ \itemize{ \item preprocessQuantile(object) would fail if object was a GenomicMethylSet. This is now fixed. \item Cleanup of Rd markdown in various help files. \item estimateCellCounts would throw an error. This is now fixed. The function arguments have changed. \item Bug in cpgCollapse led to incorrect results. Your output is affected if table(granges(output[[1]])$type) is all 'OpenSea'. Reported by Florence Cavalli . \item Encapsulated the example for estimateCellCounts() in 'dontrun', to disable it on the build servers. \item preprocessQuantile would work as if removeBadSamples=TRUE no matter the value of the argument. \item Fixing replace bug in fixMethOutliers; it would not work on the output of preprocessSWAN. Reported by David McGaughey . \item The function mapToGenome would return something that looked like an unordered GenomicMethylSet. Actually, loci were correctly ordered within chromosomes, the issue had to do with whether the chromosomes were ordered as chr1, chr2, chr3 (used in minfi) or chr1, chr10, chr11 (lexigraphically). Reported by Florence Cavalli . \item Switched to using new author format in DESCRIPTION. } } \section{Version 1.7}{ \itemize{ \item Added getMethSignal(), a convenience function for programming. \item Changed the argument name of "type" to "what" for getMethSignal(). \item Added the class "RatioSet", like "GenomicRatioSet" but without the genome information. \item Bugfixes to the "GenomicRatioSet()" constructor. \item Added the method ratioConvert(), for converting a "MethylSet" to a "RatioSet" or a "GenomicMethylSet" to a "GenomicRatioSet". \item Fixed an issue with GenomicMethylSet() and GenomicRatioSet() caused by a recent change to a non-exported function in the GenomicRanges package (Reported by Gustavo Fernandez Bayon ). \item Added fixMethOutliers for thresholding extreme observations in the [un]methylation channels. \item Added getSex, addSex, plotSex for estimating sex of the samples. \item Added getQC, addQC, plotQC for a very simple quality control measure. \item Added minfiQC for a one-stop function for quality control measures. \item Changed some verbose=TRUE output in various functions. \item Added preprocessQuantile. \item Added bumphunter method for "GenomicRatioSet". \item Handling signed zero in minfi:::.digestMatrix which caused unit tests to fail on Windows. \item addSex and addQC lead to sampleNames() being dropped because of a likely bug in cbind(DataFrame, DataFrame). Work-around has been implemented. \item Re-ran the test data generator. \item Fixed some Depends and Imports issues revealed by new features of R CMD check. \item Added blockFinder and cpgCollapse. \item (internal) added convenience functions for argument checking. \item Exposed and re-wrote getAnnotation(). \item Changed getLocations() from being a method to a simple function. Arguments have been removed (for example, now the function always drops non-mapping loci). \item Implemented getIslandStatus(), getProbeType(), getSnpInfo() and addSnpInfo(). The two later functions retrieve pre-computed SNP overlaps, and the new annotation object includes SNPs based on dbSNP 137, 135 and 132. \item Changed the IlluminaMethylatioAnnotation class to now include genomeBuild information as well as defaults. \item Added estimateCellCounts for deconvolution of cell types in whole blood. Thanks to Andrew Jaffe and Andres Houseman. } } \section{Version 1.5}{ \itemize{ \item Added unit testing for the preprocessing algorithms. \item Improved the speed of SWAN for large datasets. \item Added the new class "GenomicRatioSet". It is akin to "GenomicMethylSet" but instead of containing Meth and Unmeth it contains M and/or Beta and copy number. \item We now depend on illuminaio instead of crlmm in order to get readIDAT. \item Added unsrturl.bst to minimize dependences for running Sweave. } } \section{Version 1.3}{ \itemize{ \item Updated preprocessSwan to fix a bug when mSet was not set to the default value of NULL. Specifically, now the "counts" tables is used to construct "subset". \item Changed the function manifestNew() to IlluminaMethylationManifest(). \item Added IlluminaMethylationAnnotation(). \item Added placeholders for unit testing based on RUnit. \item Introduced a new show method for MethylSet and RGChannelSet, derived from the eSet method in Biobase. \item The annotation slot of a MethylSet/RGChannelSet is now intended to _not_ be a scalar, but instead have length 2 with components 'array' and 'annotation'. This foreshadows introdution of annotation packages for use with minfi. \item Reorganization of R files; rewriting of the man pages for MethylSet, RGChannelSet. \item getMeth, getUnmeth, getBeta, getM are now methods. \item bug fix to qcReport thanks to Tao Shi. \item Changes to getBeta / getM, both in terms of which arguments the methods take and how the values are computed. \item Changes to the manifest structure; it now has separate slots for genotype probes and these probes are no longer part of a MethylSet (using eg. preprocessRaw). They can be accessed using getProbeInfo(rgSet, type) with type equal to "SnpI" or "SnpII". \item Introduction of mapToGenome, getLocations and the new class GenomicMethylSet. man pages are reasonably complete, still need to add examples to the vignette. This will be a standard part of an extended pipeline. \item Introduction of IlluminaHumanMethylation450lannotation.ilmn.v1.2 which contains some new annotation needed for mapToGenome/getLocations. This package will be split into several packages moving forward, in an attempt to harmonize efforts by us and Tim Triche. getLocations/mapToGenome will stay the same. \item getControlTypes added (returns the different types of control probes). \item GenomicMethylSet now inherits a number of methods including granges(), start(), end() etc. from SummarizedExperiemnt. They have therefore been deleted from minfi. \item Bugfix to getLocations(..., mergeManifest = TRUE). It now longer throws an error. \item mapToGenome now returns a GenomicMethylSet ordered according to the chromosome name ordering chr1,..,chr22,chrX,chrY,unmapped, the last one not present if drop=TRUE (default). } } \section{Version 1.1}{ \itemize{ \item Changed NAMESPACE file \item Defined constructors for MethylSet, RGChannelSet, RGChannelSetExtended. \item Included a version number in the class definition for MethylSet and RGChannelSet. Old objects can be updated by calls of the form updateObject(Mset). \item read.manifest (not exported) updated to include nCpGs. \item preprocessSwan was added. Still work in progress. \item Changed background calculation in preprocessSwan. \item Added a section to the vignette describing preprocessSwan. \item Bug fix: ilogit2 is now in base (it used to be base e). Thanks to Time Triche, Jr . \item Added and dcoumented the IlluminaMethylationAnnotation class; still work in progess. \item Moved package vignette from inst/doc to vignettes. } } \section{Version 0.99}{ \itemize{ \item Initial release to Bioconductor. \item Added NEWS file. \item Bugfix to vignette. \item readIDAT is now exported by crlmm, implying that we can import this function through NAMESPACE. } }
