SeqArray - Bioconductor Release 3.16

CHANGES IN VERSION 1.38.0

UTILITIES

• new option 'ext_nbyte' in seqGet2bGeno()
• seqAlleleCount() and seqGetAF_AC_Missing() return NA instead of zero when all genotypes are missing at a site
• seqGDS2VCF() does not output the FORMAT column if there is no selected sample (e.g., site-only VCF files)
• seqGetData(, "$chrom_pos2") is similar to seqGetData(, "$chrom_pos") except the duplicates with the suffix ("1", "2" or >2)

NEW FEATURES

• seqGDS2BED() can convert to PLINK BED files with the best-guess genotypes when there are only numeric dosages in the GDS file
• seqEmptyFile() outputs an empty GDS file

SeqArray - Bioconductor Release 3.15

CHANGES IN VERSION 1.36.0

NEW FEATURES

• new functions seqUnitCreate(), seqUnitSubset() and seqUnitMerge()
• new functions seqFilterPush() and seqFilterPop()
• new functions seqGet2bGeno() and seqGetAF_AC_Missing()
• new function seqGetData(, "$dosage_sp") for a sparse matrix of dosages
• the first argument 'gdsfile' can be a file name in seqAlleleFreq(), seqAlleleCount(), seqMissing()
• new function seqMulticoreSetup() for setting a multicore cluster according to a numeric value assigned to the argument 'parallel'

UTILITIES

• allow opening a duplicated GDS file ('allow.duplicate=TRUE') when the input is a file name instead of a GDS object in seqGDS2VCF(), seqGDS2SNP(), seqGDS2BED(), seqVCF2GDS(), seqSummary(), seqCheck() and seqMerge()
• remove the deprecated '.progress' in seqMissing(), seqAlleleCount() and seqAlleleFreq()
• add summary.SeqUnitListClass()
• no genotype and phase data nodes from seqSNP2GDS() if SNP dosage GDS is the input

BUG FIXES

• seqUnitApply() works correctly with selected samples if 'parallel' is a non-fork cluster
• seqVCF2GDS() and seqVCF_Header() work correctly if the VCF header has white space
• seqGDS2BED() with selected samples for sex and phenotype information
• bug fix in seqGDS2VCF() if there is no integer genotype

SeqArray - Bioconductor Release v3.13

CHANGES IN VERSION 1.32.0

NEW FEATURES

• new option 'ret.idx' in seqSetFilter() for unsorted sample and variant indices
• new option 'ret.idx' in seqSetFilterAnnotID() for unsorted variant index
• rewrite the function seqSetFilterPos(): new options 'ref' and 'alt', 'multi.pos=TRUE' by default
• new option 'packed.idx' in seqAddValue() for packing an indexing variable
• new option 'warn' in seqSetFilter() to enable or disable the warning
• new functions seqNewVarData() and seqListVarData() for variable-length data

UTILITIES

• allow no variant in seqApply() and seqBlockApply()
• the list object returned from seqGetData() always have names if there are more than one input variable names

BUG FIXES

• seqGDS2VCF() should output "." instead of NA in the FILTER column
• seqGetData() should support factor when '.padNA=TRUE' or '.tolist=TRUE'
  
• fix seqGDS2VCF() with factor variables
• seqSummary(gds, "$filter") should return a data frame with zero row if 'annotation/filter' is not a factor

SeqArray - Bioconductor Release 3.10

CHANGES IN VERSION 1.26.0

NEW FEATURES * new function seqAddValue()

UTILITIES * RLE chromosome coding in seqBED2GDS() * change the file name "vignettes/R_Integration.Rmd" to "vignettes/SeqArray.Rmd", so vignette("SeqArray") can work directly * correct Estimated remaining Time to Complete (ETC) for load balancing in seqParallel()

BUG FIXES * seqBED2GDS(, verbose=FALSE) should have no display

CHANGES * use a svg file instead of png in vignettes

SeqArray - Bioconductor Release 3.9

CHANGES IN VERSION 1.24.0

NEW FEATURES

• a new function seqResetVariantID()
• a new option in seqRecompress(, compress="none") to uncompress all data
• seqGetData() allows a GDS file name in the first argument

- C++

SeqArray - Bioconductor Release v3.8

CHANGES IN VERSION 1.22.0

UTILITIES

• avoid duplicated meta-information lines in seqVCF2GDS() and seqVCF_Header()
• require >= R_v3.5.0, since reading from connections in text mode is buffered
• seqDigest() requires the digest package
• optimization in reading genotypes from a subset of samples (according to gdsfmt_1.17.5)

NEW FEATURES

• seqSNP2GDS() imports dosage GDS files
• seqVCF_Header() allows a BCF file as an input
• a new function seqRecompress()
• a new function seqCheck() for checking the data integrity of a SeqArray GDS file
• seqGDS2SNP() exports dosage GDS files

BUG FIXES

• seqVCF2GDS() and seqVCF_Header() are able to import site-only VCF files (i.e., VCF with no sample)
• fix seqVCF2GDS() and seqBCF2GDS() since reading from connections in text mode is buffered for R >= v3.5.0

SeqArray - backward compatibility for ≤ R_3.4.4

Reading from connections in text mode is buffered for >= R3.5.0. No use buff in the new version (>=3.5.0) of R_ext/Connections.h: ```c struct Rconn { ... unsigned char *buff; sizet bufflen, buffstoredlen, buffpos; }; ```

SeqArray - SeqArray package with a slow version of seqVCF2GDS()

• SeqArrayv1.11.18 is backward compatible with Rv2.15.0
• the later version will require R (>=v3.3.0), which utilizes the official C API R_GetConnection() to accelerate text import and export
