Please keep the namd-l mailing list in the loop so that others can benefit from the discussion. By the way, did you search in the namd-l and vmd-l archive for entries similar to your problem?

 

Once again, the details that you provided are not sufficient for any diagnostic. You need to send us the real problem, not describing your case in general and vague terms as “proper topology”. Also, please share the error messages that the program prints in the console. Most of the time, they are self-explanatory.

 

But let me try to guess here. When generating the psf and pdb files using psfgen, please make sure that your original pdb and topology file have the same residue name and atoms’ name. They need to match, otherwise, errors will occur.

 

Best,

 

João

Sir i was trying to generate the psf file for protein ligand complex by giving the proper topology file for ligand(generated using swissparam) also while generating psf file it is deleting some of ligand atoms.

Dear Shobhit,

 

You will need to provide details of what and how you are doing so we can help you. Please provide as many details as you can.

Are all these messages related to the sphere model that you asked previously?

 

Best,

 

João

Dear sir/maam
