BRGenomics 0.99.33

• Add support for log fold-change shrinkage in getDESeqResults()
• Minor bugfix generating a warning under some conditions when non-integer binsizes are used

BRGenomics 0.99.30

• Added options in mergeReplicates()
• Various small doc updates and minor internal changes

BRGenomics 0.99.23

• Added support for non-basepair-resolution GRanges throughout, via the expand_ranges argument
  • Substantial performance benefits for less-sparse datasets (e.g. whole read coverage)
  • Supported everywhere, including counting functions, subsampling, merging, normalization, etc.
• Rewrite of mergeGRangesData():
  • Substantial performance improvements for most datasets
  • No longer requires basepair-resolution GRanges objects
  • Added options and flexibility for merging reads as well as coverage data

• subsampleGRanges() no longer returns a basepair-resolution GRanges by default
• When field=NULL, applyNFsGRanges() no longer returns a basepair-resolution GRanges by default
• Add use_bin_numbers option to n-dimension binning functions; setting to false allows returning of bin values (the bin center) instead of the ordinal bin numbers (indexes)
• Quietly adding support for GRangesList objects (not fully tested)

BRGenomics 0.99.15

• Add pre-filtering to counting functions for performance
• Some additional clarification of readcounts vs. coverage signal in counting and import functions

BRGenomics 0.99.10

• Code modifications to pass Bioconductor test builds on Windows:
  • Make all examples and tests single core
  • Internally (not exported) redefine mcMap (current implementation in package parallel needs to be modified)
  • In tests and examples, test if on Windows before attempting any bigWig file import

BRGenomics 0.99.0

• Changes for Bioconductor submission:

• Various minor formatting changes to codebase

BRGenomics 0.8.1

• Updated included external datasets to be much smaller
  • Included bam file now <200 reads
  • Included bigWig and bedGraph files derived from the bam file
• Minor update to vignette to reflect the change in the bam file
• Updated the included data() objects (PROseq and PROseq_paired)
