sam format version in tophat output

[tangx_2010]

Hi，
Tophat calls samtools when it outputs alignments. The version of samtool in my machine is 0.1.13(r926:134), which is newly developed . However, the sam format version indicated in the header of tophat *.bam result shows VN:1.0, which is very old. I don't know why.

The "VN:1.0" is not the samtools version, but the SAM specification version. Samtools 0.1.13 reports that it still confirms with spec 1.0 and onwards.

Thank you very much! This really helped me a lot.
