I am trying to pull a specific GenBank entry off of the NCBI database using the genbankr library. My hope was to have all the feature information in a more "R friendly" (e.g. GRanges) format so I could incorporate it into my analysis. Other IDs seem to work but this one was giving me trouble.

This is the location of the entry on the web:

https://www.ncbi.nlm.nih.gov/nuccore/AJ000387.1

I tried both downloading the entry manually (.gb file - both 'full' and 'standard') and loading into the program by calling the following functions, respectively:

gb = readGenBank('./zam.gb')

and

gba = GBAccession("AJ000387.1")
gb = readGenBank(gba, partial=TRUE)

Apparently this format should be possible to import (and works for other GenBank entries) but I am running into some strange error:

Annotations don't have 'locus_tag' label, using 'gene' as gene_id column
Annotations don't have 'locus_tag' label, using 'gene' as gene_id column
Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘getListElement’ for signature ‘"GRanges"’

Is there any easy way to fix this and/or is this a type of entry the package cannot handle by nature?

Thanks for your time.

Ben
