Question Posted 10/27/14:
I find only 717 VCF files within the 25 zip archives I downloaded from (see listing below). I would expect 809 files, according to ADNI_WGS_Notice_20130917. Did I miss something ?

There are 29 sets of WGS data. If you downloaded 25 sets, that might be the reason that you have 717 VCF files instead of 809.
