of selected samples, # of selected variants) instead of 2 integers CHANGES IN VERSION 1.10.0-1.10.6 ------------------------- o the version number was bumped for the Bioconductor release version 3.2 o fix a memory issue in `seqAlleleFreq()` when 'ref.allele' is a vector o `seqSetFilter()` allows numeric vectors in 'samp.sel' and 'variant.sel' o `seqSummary()` returns ploidy and reference o `seqStorage.Option()` controls the compression level of FORMAT/DATA o `seqVCF2GDS()` allows extract part of VCF files via 'start' and 'count' o `seqMerge()` combines multiple GDS files with the same samples o export methods for compatibility with VariantAnnotation o a new argument '.useraw' in `seqGetFilter()` o a new argument 'allow.duplicate' in `seqOpen()` o fix a bug in `seqParallel()` (https://github.com/zhengxwen/SeqArray/issues/11) and optimize its performance o 'gdsfile' could be NULL in `seqParallel()` CHANGES IN VERSION 1.9.0-1.9.19 ------------------------- o a new function `seqGDS2SNP()` o supported by the SNPRelate package o support `seqApply(..., margin="by.sample")` o new functions `seqOptimize()`, `seqMissing()`, `seqAlleleFreq()`, `seqNumAllele()` and `seqSetFilterChrom()` o "intersection" and "push+intersection" in `seqSetFilter()` o parallel implementation in `seqNumAllele()`, `seqMissing()` and `seqAlleleFreq()` o a new function `seqExport()` o new argument ".useraw" in `seqApply()` o fix a bug for duplicated "variant.id", https://github.com/zhengxwen/SeqArray/issues/7 o fix an issue of `seqVCF2GDS()` when there are duplicated format or info ID o improve access speed (+50%, benchmark on calling seqApply(..., FUN=function(x) {})) o new functions `seqSNP2GDS()`, `seqBED2GDS()`, `seqAlleleCount()` and `seqResetFilter()` o `seqCompress.Option()` is renamed to `seqStorage.Option()` o "ZIP_RA" is the default value in `seqStorageOption()` and other functions instead of "ZIP_RA.max" o `seqSetFilter()` becomes a S4 method CHANGES IN VERSION 1.8.0 ------------------------- o The version number was bumped for the Bioconductor release version 3.1 CHANGES IN VERSION 1.7.1-1.7.5 ------------------------- o bug fix in getting genotypes if position > 2^31 o add an option 'ignore.chr.prefix' to the function `seqVCF2GDS()` o `seqVCF2GDS()` ignores the INFO or FORMAT variables if they are not defined ahead o a new action 'push+set' in the function `seqSetFilter()` o bug fix if 'requireNamespace("SeqArray")' is called from other packages CHANGES IN VERSION 1.6.0 ------------------------- o The version number was bumped for the Bioconductor release version 3.0 CHANGES IN VERSION 1.5.1-1.5.2 ------------------------- o fix a bug in `seqVCF2GDS()` when the values in the FILTER column are all missing o enhance `seqVCF.Header()` o support the LinkingTo mechanism o fix the error in haploid genotypes (Y chromosome) CHANGES IN VERSION 1.4.0 ------------------------- o The version number was bumped for the Bioconductor release version CHANGES IN VERSION 1.3.1-1.3.4 ------------------------- o update according to the new version of VariantAnnotation o update test codes to avoid the conflict o bumped version as all packages that depend on Rcpp must be rebuilt o modify to new biocViews to DESCRIPTION file CHANGES IN VERSION 1.2.0 ------------------------- o The version number was bumped for the Bioconductor release version CHANGES IN VERSION 1.1.4-1.1.5 ------------------------- o add a new argument "action" to the function `seqSetFilter()` o add a new function 'seqInfoNewVar' which allows adding new variables to the INFO fields o minor bug fix in asVCF o update man page "SeqVarGDSClass-class.Rd" with new methods o in DESCRIPTION, BiocGenerics listed in "Suggests" instead of "Imports" as suggested by R CMD check o bug fix in seqDelete o revise the function 'seqTranspose' according to the update of gdsfmt (v1.0.0) CHANGES IN VERSION 1.1.1-1.1.3 ------------------------- o revise the argument 'var.index' in the function `seqApply()` o basic supports of 'GRanges' and 'DNAStringSetList' o added methods 'qual', 'filt', 'asVCF' o 'granges' method uses length of reference allele to set width o minor bug fix to avoid `seqGetData()` crashing when no value returned from a variable-length variable o update documents CHANGES IN VERSION 1.0.0 ------------------------- o The version number was bumped for the Bioconductor release version CHANGES IN VERSION 0.99.0 ------------------------- o first submission
