Strange AD Value due to Select Variants

Hi,

I've used the Unified Genotyper for variant calling with GATK version 2.5.2. This was the info for a private variant.

GT:AD:DP:GQ:PL
0/1:52,37:88:99:1078,0,1486

However, after select variants to exclude non variant and variants not passing Filter, the AD changed and eliminated the alternative reads though the DP remained unchanged.

GT:AD:DP:GQ:PL
0/1:51,0:88:99:0,99,1283

I think I recall another post having a similar issue due to multithreaded use of select variants

APologies for not commenting on this post instead as I had already posted this prior to seeing the other post!

Thanks,

MC
