Take a look in your Apache error log files to see if there
are any error messages about your track from the browser CGI
binaries.  The messages should have appeared when you loaded
the tracks, but maybe something else is going wrong.

Subject: [Genome] empty data for BAM tracks

Hi all,

I just uploaded some of our new data to our local UCSC mirror (which is 
locally accessible only). The data is in BAM format, and is hosted in 
another server locally which, again is visible only locally (so 
unfortunately I can not test the same BAM files with UCSC Browser). The 
problem is I can not see any data in the track, just blank. There are 
two points:
     - Our local mirror works fine with other dataset (in BAM format)
     - The pipeline analysis we use (to produce BAM) using samtools, and 
all other dataset we have run also use the same pipeline
That means there is no difference between this BAM dataset and other 
dataset we have done so far. I also use samtools to view the BAM files, 
and they look fine to me.

So any body has idea why this suddenly happened? What "quick and easy" 
things should we do to debug the situation before we upload our BAM 
files to somewhere outside to test with the real UCSC?

Thank you very much,

D.
