[phenixbb] Two ions at same position

I'm in the process of installing a local BLAST server for doing blast 
protein queries. As I understand it I need a file with all the FASTA 
sequences as input for initially generating my local BLAST database. The 
one present in ftp://ftp.rcsb.org/pub/pdb/derived_data/pdb_seqres.txt 
seems to contain redundant entries. Querying it produces many extra PDB 
chain-ids when compared to a BLAST query on the NCBI web server.

Does anyone know where to get a non-redundant version of FASTA records 
so that I can create a similar database as the one used by NCBI?

Many thanks,
