[Gmod-ajax] JBrowse subfeatures repeating bug?

[Vaneet L. <van...@uc...>]

Hi,

I'm not sure if anyone's already run into this bug before, at least it certainly seems like a bug.  When I click on my gene model in JBrowse, and then click on subfeatures under a given mRNA, the same 3'UTR or 5'UTR segment gets displayed multiple times as duplicates with the same coordinates (screenshot attached).  It doesn't matter which model I select or even under which species or genome for that matter that it's under, it always appears repeated like that in the details window.  Here's a trimmed down version of the hhex.S gene that's in the screenshot from my GFF3 (column 9 attributes trimmed off) just so it can fit here:

Chr7S   Gnomon  gene    15890549        15902647        .       -       .       ID=XBXL10_1g32594;Name=hhex.S
Chr7S   Gnomon  mRNA    15890549        15902647        .       -       .       ID=XBmRNA61523;Parent=XBXL10_1g32594
Chr7S   Gnomon  exon    15902179        15902647        .       -       .       ID=XBexon785823;Parent=XBmRNA61523
Chr7S   Gnomon  exon    15896206        15896384        .       -       .       ID=XBexon785824;Parent=XBmRNA61523
Chr7S   Gnomon  exon    15894761        15894811        .       -       .       ID=XBexon785825;Parent=XBmRNA61523
Chr7S   Gnomon  exon    15890549        15891175        .       -       .       ID=XBexon785826;Parent=XBmRNA61523
Chr7S   Gnomon  CDS     15902179        15902551        .       -       0       ID=XBcds718348;Parent=XBmRNA61523
Chr7S   Gnomon  CDS     15896206        15896384        .       -       2       ID=XBcds718348;Parent=XBmRNA61523
Chr7S   Gnomon  CDS     15894761        15894811        .       -       0       ID=XBcds718348;Parent=XBmRNA61523
Chr7S   Gnomon  CDS     15890948        15891175        .       -       0       ID=XBcds718348;Parent=XBmRNA61523

I have this setting enabled in my track to draw out the 'implied' UTRs which aren't directly supplied in the GFF3 file:

        "impliedUTRs" : true,

Has anyone run into this before?  Is it a technical bug?  Why is it happening?

Thanks,

Vaneet
