All the results pertain to release 10 of The SNP Consortium (http://snp.cshl.org)
The chromosomal assembly files used for chromosomes 21 and 22 were obtained from the following URLs:

1. ftp://ftp.sanger.ac.uk/pub/human/chr22/sequences/Chr_22/complete_sequence/Chr_22_19-05-2000.fa
2. ftp://ncbi.nlm.nih.gov/genbank/H_sapiens
These sequences can be found in the 'seqs' directory.  It is a single line concatenation of the sequence file.


In all these files, the columns pertain to the following:

snpid: The SNP Consortium (TSC) identifier for SNPs
snppos: The position of the SNP with respect to an absolute chromosomal coordinate framework.
swp_match: The name of the protein in SWISS-PROT
