Thanks Pierre. I'm interested in downloading some complete genomes from the PGP, and then filtering out common variants using dbSNP.
Before doing this, however, I need to remove PGP-deposited data from dbSNP, to avoid filtering the genomes against themselves! That's why I wanted to know if the PGP data was in dbSNP or not.
It does look like most of the PGP has never been deposited though. This is a bit surprising, but does make my job easier.
