I can find this description online: QNAME: Query template NAME. Reads/segments having identical QNAME are regarded to come from the same template. A QNAME ‘*’ indicates the information is unavailable. In a SAM file, a read may occupy multiple alignment lines, when its alignment is chimeric or when multiple mappings are given.

The qname example is: M04402:7:000000000-ANGUV:1:2103:23029:8212	

This is from a Miseq run, so what is the meaning of these number?

Thanks!!



If you are only interested in the meaning of that header (referred to as `qname` in SAM format) then check [this link][1].
