Dear Sir,

Thank you so much for your reply and suggestion. It's working after I typed
'source'. Now, I am using chamber command
under parmed interpreter using the following

chamber -top top_all36_prot.rtf -param par_all36m_prot.prm -psf
Willbold_IRF_1-42_6X2.psf -crd Willbold_IRF_1-42_6X2.pdb

It is now working now. However, I am receiving some chamber failure with
some warning which is attached herewith the mail.
Please help me to fix this issue or let me know if it is fine to move

Thank you,
