Hi,

I have previously used gulp outside Materilas Studio for my simulations and now I would like to import them into MS. when I import a *.gin file in MS and try to say, run an optimization using the gulp implemented inside MS I get into error which reads:

Error in job preparation.

Unable To Copy File to: .\Polyvinyl_alcohol GULP GeomOpt\Polyvinyl_alcohol.trjaux.

The system cannot find the file specified.

My guess is MS needs a 3D file, is that right? I know I can convert my files to arc but isn't there any way to just start MS with a gin file?

Also I noticed taht there a veriaety of force fields (PCFF, CVFF, Compass) in modules such as Forcite and Discover but there are not available for gulp. Is there a particular reason for that.

Thank you in advance
