Accessible Surface Area (ASA)

This module allow users to predict accessible surface area (ASA) in their protein. Basically accessible surface area are assigned in a query protein based on its similarity with known protein structure in PDB. This module allow users to select desired BLAST parameters for performing similarity search. Advanced option further facilitate users in selecting most appropriate parameters. There are three non-redundant database againt which BLAST can be performed: 40%, 70% and 100%.
