I can retrieve the chromosome names stored in a GRanges object either using GenomeInfoDb::seqnames() or rtracklayer::chrom(). This deviates from the use of the other accessor functions, such as BiocGenerics::start(), BiocGenerics::end(), etc
Is there a reason for this split up? Is there a best practice, which function (seqnames or chrom) to use?
Thanks for the suggestions.
