Tips and Hints

File Conversions

*.val is an ASN.1 binary file used by NCBI and TraDES.
It contains the 3D structure information and can be converted into a PDB file...

use the command:
valtopdb -f structure.val -m 1 -p structure.pdb to convert a *.val file into a PDB file.

See the FAQ page (Question #2) for how to convert a PDB file into a *.val file.

Use the command
val2prt -f structure.val
To convert the ASN.1 binary into ascii (readable) ASN.1


For better structures (but slower) use the -m option which will perform a CHARMM minimization on the structure before writing it out.  This is helpful for the unfolding methods.
