CreateGermlines.py provides incorrect germline

I was looking at mutation frequencies for a dataset and found about ~10% to be highly mutated (in the range of 40%). These sequences are functional and not really mutated that much. However, the GERMLINE_GAP_D_MASK sequence is totally off!

The IMGT zip file can be found here: /scratch2/kleinstein/klarenbeek_gut/data2.0/03.IMGT/Healthy_Ig/Healthy_Ig_part000001.zip

I'm attaching a TAB file containing a few of these sequences
