Hi, Kevin! It looks like your apache says it will accept byte-range requests, i.e. it includes this in the response header when you query the server: Accept-Ranges: bytes
But when we actually do send the range request, your server ignores it and just sends back the entire file, and 200 instead of 206 partial content. My guess is that you have a line like this somewhere in your apache configuration that should be considered for removal: RequestHeader unset Range If that line exists in your configuration, it will strip out all incoming range requests. Looking at apache history, between version 2.0 and 2.0.54, there was a denial of service bug that affected reverse-proxy which could allow attackers to cause the server to waste ram. Since you now have version 2.2, that apache bug is irrelevant and you should be safe to allow range requests. bigDataUrl in custom tracks will not work without range requests. -Galt 2/9/2011 9:43 AM, Kevin LEBRIGAND: > Sorry for that. > I've restored the file > here is the custom track i paste in UCSC custom tracks: > track type=bam name="myTest" description="miRNAs hg19" db=hg19 > visibility=pack bigDataUrl=http://www.microarray.fr/data/public/tmp/myTest.bam > browser position chr17:57,918,627-57,918,698 > > Samtools view at this position returns 142322 reads but i see nothing in UCSC > web browser. > > I've a second question maybe from the same issue: > i've tryed to visualize .bw file generated from my .bam file as follow: > $> genomeCoverageBed -bg -ibam myTest.bam -g hg19.chrsize> myTest.bedGraph > $> bedGraphToBigWig myTest.bedGraph hg19.chrsize myTest.bw > > UCSC custom tracks: > track name="Wiggle Track" type=bigWig bigDataUrl=http://myserver.edu/sample.bw > > I got an error: > http://www.microarray.fr/data/public/tmp/myTest.bw is not a chromosome id > r-tree index file > > thanks angie for your help. > best > kevin. > > > > > > Kevin LEBRIGAND > 2011-02-09 > _______________________________________________ > Genome maillist - [email protected] > https://lists.soe.ucsc.edu/mailman/listinfo/genome _______________________________________________ Genome maillist - [email protected] https://lists.soe.ucsc.edu/mailman/listinfo/genome
