[Gmod-gbrowse] "hide empty subtracks" not working - bigwig metadata file

[Haiming Wang]

Hi,


It appears that GBrowse does not even display subtrack headers when there is no data to display, as shown by the blank spaces in the image attached, which should display eight subtracks instead of six. "hide empty subtracks" is set to false. The following is the related config. I wonder if anyone has any idea about this issue? Thanks!


[tgonME49_DBP_Hehl-Grigg_rnaSeq_RSRC:database]
db_adaptor = Bio::DB::BigWigSetEuPath
db_args = sub { { -index => '/path/tgonME49_DBP_Hehl-Grigg_rnaSeq_RSRC/metadata' } }

[tgonME49_DBP_Hehl-Grigg_rnaSeq_RSRCCoverage]
feature = Coverage
database = tgonME49_DBP_Hehl-Grigg_rnaSeq_RSRC
glyph = wiggle_xyplot
no_grid = 1
height = 40
key = Transcriptomes of Cat Enteroepithelial Stages (CZ-H3) ...
bgcolor = sub { GBrowse::Display::rnaseqColorFromBigWig(shift) }
scale = both
autoscale = local
link = javascript:void(0)
category = Transcript Expression Evidence: B. RNA-seq: T gondii ME49 mRNA-seq: Logged
group_label = 0
group_label_position = top

hide empty subtracks = 0

Hi Haiming,

I am guessing this is a side effect of having empty tracks. The space is almost certainly allotted prior to rendering the track, and no returned data from the database adaptor means no subtrack is rendered, which also means no subtrack title as it would be rendered with the xyplot data.

One possible workaround would be to munge the raw wig data and include 0s at all positions rather than no (null) data, so that the graph would have something (even if it’s just a bunch of 0s) to draw.

Unfortunately, I’m not familiar enough with the code to suggest a real fix.

Hi Tim,

Thanks a lot for your suggestion! I agree that include 0s at raw wig data should help in this case. I'm afraid that we might have removed 0s while converting raw scores into log scale. But, it would be ideal if wiggle_xyplot can always display a subtrack title even for empty region.

Best,
-Haiming
