[Gmod-help] Gbrowse fails with too many tracks

Tue Sep 21 15:31:50 EDT 2010

Hey -

Thanks for the response.  Here're my answers; let me know if there's
anything else I should send to help.

Generic Genome Browser Version 1.70, with BioPerl etc. up to date
(since I'd updated pretty much everything in the last few weeks to get
GBrowse2 going, though I can give details on different modules and so
on if necessary.)   And no, the plugins I am using are BatchDumper,
FastaDumper, RestrictionAnnotator, FilterTest, and Submitter, so I
doubt that it is VistaPlot.  Furthermore, when none of these other
plugins are activated, I get identical errors.

Generic Genome Browser version 2.14.  The GFF3 file and the genome and
general GBrowse configuration files are attached.  The yeast and
volvox conf files (not attached) are unchanged from stock except for
the choice of db_adaptor and db_args, and the addition of the user and
pass fields for their databases.  The conf file for my genome is
essentially the volvox conf file, with information adapted to fit my
data (e.g. default features are genes, not the volvox example
features.)

Thanks!

-Grace
