Hello Ian, This may be a function of the size of individual data points. If the data is small and the view is comparatively large (zoomed out), this can graphically produce hidden, single-pixel, or other uninformative views.
Would you like to send a link to a Session with the data loaded or an http/ftp location where I can access the input file so that I can load it as a custom track and have a look? You can send the information directly to me (not the entire list). Along with the data, please send the exact browser and track lines you used to load the data. Also include the chromosome locations you used. This will ensure that we are looking at the same view when discussing the issue. Thanks, Jennifer ------------------------------------------------ Jennifer Jackson UCSC Genome Bioinformatics Group ----- "Ian Donaldson" <[email protected]> wrote: > From: "Ian Donaldson" <[email protected]> > To: [email protected] > Sent: Tuesday, January 19, 2010 2:01:42 AM GMT -08:00 US/Canada Pacific > Subject: [Genome] Yeast sacCer2 bigBed file problem > > I have constructed a bigBed file from a BED file containing 50bp next > > gen. sequencing reads.
