Notes about the FAS file extension:

Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

The FAS file type is primarily associated with 'FASTA Format'. FASTA is a DNA and Protein sequence alignment software package first described (as FASTP) by David J. Lipman and William R. Pearson in 1985 in the article Rapid and sensitive protein similarity searches. The original FASTP program was designed for protein sequence similarity searching. FASTA format files often have file extensions like .fa, .mpfa, .fna, .fsa, .fas or .fasta.

Cannot access FAS files on windows?

When windows gives you an error message saying that it
"Cannot open FAS files", this means either:

A. You need to identify a program that can open the file
B. Or your registry may be damaged

RECOMMENDED:

In both cases it is strongly recommended that you
run a free scan for registry errors.
