Hi all, I have been trying to view some custom tracks, which are made of bigBed files with a small number of features but lots of blocks (exons) for each feature. There should be thin lines between the blocks but often the Genome Browser will just display a thick block for the whole region. There does not seem to be any consistent way to predict which features get displayed as a thick block instead of correctly as alternating thin and thick blocks. Simply reloading the page without changing anything else will yield a new crop of thick blocks.
I can demonstrate this at this region, loading one bigBed file as two separate tracks: http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg19&position=chr18:3447551-3460100&hgt.customText=http://noble.gs.washington.edu/~mmh1/2012/outbox/ucsc/bigbed-display-bug/segway.browser For me, the two identical copies do not display identically. Even right-clicking on the image and selecting "View image" twice will yield two different images (with differences between the identical copies within): View 1 ("Copy 2" shows the expected results): http://noble.gs.washington.edu/~mmh1/2012/outbox/ucsc/bigbed-display-bug/hgt_genome_2aa8_2fe600.png View 2: http://noble.gs.washington.edu/~mmh1/2012/outbox/ucsc/bigbed-display-bug/hgt_genome_2ab6_2fe670.png At the downstream edge of features the display is even stranger. The unexpected thick blocks turn into a block of medium thickness and extend to the downstream. For example, see this: http://noble.gs.washington.edu/~mmh1/2012/outbox/ucsc/bigbed-display-bug/hgt_genome_4690_303510.png Browser information: Firefox 12.0 Linux 2.6.18-274.el5 RHEL5 Can this be fixed? Is there a way for me to work around this until it is fixed?
