bam file visualization / cigar line starting with soft clips #229

Closed chklopp closed 11 years ago

chklopp commented 11 years ago

Hi,

I've upload a RNA-Seq bam file in a local instance of jbrowse 1.8.1. The spliced reads are not well positionned on the reference. It seems that the alignments having a soft clip at the begining of the cigar line are not correctly placed.

Is there script to run before adding the bam track?

Definitely sounds like a bug somewhere in the BAM handling. Would you be able to send me a link to your JBrowse instance that exhibits the problem so I could look at it directly?

http://genotoul.toulouse.inra.fr/~klopp/JBrowse-1.8.1/index.html?data=Test4665765767 Choose scaffold1 position 6500 to 9500.

The reads are not in line with the prediction because of the soft clips.

I tried just now and could not connect to it. Is the server down?

chklopp commented 11 years ago

Try,

I'm having a problem viewing the BAM files on that server, I think you might have Apache's mime_magic module enabled, see: http://www.gmod.org/wiki/JBrowse_Configuration_Guide#Apache_Configuration_Note

chklopp commented 11 years ago

Could you retry. http://genoweb.toulouse.inra.fr/~klopp/JBrowse-1.8.1/index.html?loc=scaffold1%3A6979..8707&tracks=DNA%2CAUGUSTUS%2C454%20RNA-Seq%20STAR%2C454%20RNA-Seq%20STAR%20al2%2Cstar&data=Ganoderma

Here is the picture I get from IGV for scaffold1:6505..9962

Cheers

Could you try again to attach the IGV picture to the issue? It didn't come through.

rbuels commented 11 years ago

The server issue seems fixed now, though.

rbuels commented 11 years ago

i think this is probably fixed now in master, the fix will be coming out in JBrowse 1.9.0

chklopp commented 11 years ago

Hi,

I still get the same result using the latest code of the master. Th code contains the latest modification linked in git.

Cheers

Christophe
