Hi Gabriel, 

I was trying to use your package to read a Genbank file but it failed with the following error: 

> gb = readGenBank(gbFile, verbose = TRUE)
Error in validObject(.Object) : 
  invalid class “GRanges” object: 'mcols(x)' is not parallel to 'x'

       elementMetadata = mcols, seqinfo = seqinfo)
5: new_GRanges("GRanges", seqnames = seqnames, ranges = ranges, 
       strand = strand, mcols = mcols, seqlengths = seqlengths, 
       seqinfo = seqinfo)
4: GRanges(seqnames = stk$seqnames, ranges = IRanges(start = stk$start, 
       end = stk$end), strand = stk$strand)

Do you know what would be the reason for this error? 

Thanks,

Monther,

Apologies for not responding sooner. I'm not familiar with this error. I haven't seen it before. Can you provide me the gbk file in question so I can do some debugging?

Thanks,

~G
