Dear Sirs

I have tried to add external force field in Discover module of Materials Studio 5.5 but unfortunately so far I have not succeed. I copied 3 files (*.frc, *.rlb, *.dat) to directory C:\Program Files (x86)\Accelrys\Materials Studio 5.5\share\Discover\res and tried to add the force field using Discover setup. After this when I try to run calculations I always get the same error:

randomSeed is set to 835200

Line   7:BTCL> autoEcho off

Error: IO handler: Cannot find forcefield files for 'pcff_phyllosilicates'

    invoked from within

"begin forcefield = pcff_phyllosilicates"

I tried also to change names and directory of files but still I had the same problem. I would be very grateful for any help.

Greetings

Korcio
