Hi,
I want to analyse 454 data that cover exonic as well as intronic regions. Is it possible to hold this information in the bam and sam files ?
I could imagine to either (i) label each sequence position with a char, telling whether the position is in a exon or intron or (ii) have some string saying 1-100:intron;101-400:exon. I think the first way would provide better flexibility and is easier to read, but would consume more file size.
I also looked in the sam/bam doc but I didnt find any possibility to customize.
So is it possible to simply add my own fields into the sam and bam ? Would this recognized by the samtools sam/bam parsers ?
Thanks,
plichel
