[Biopython] Generating high seq similar lists

[George Devaniranjan]

Hi,

Not directly related to biopython but I am trying to use biopython to
generate a substitution matrix.

I was looking for a list of PDB, with high sequence similarity (>75%) but
less than 90%-so something like that at 1.6A or better resolution to create
my own substitution matrix.

I looked at http://dunbrack.fccc.edu/PISCES.php

But I cannot specify a range for the sequence similarity, any other way I
can get a similar list?

Thank you,
George
