Hello,

Thank you for your response. I uploaded the psf and pdb file at the top of
the tab and then clicked the load button. This did not resolve the issue.
However, I upgraded my VMD to the latest version, and it resolved
the issue. I am able to visualize the dihedral scans now.

Thank you for your help and support.

Kind regards,
Akash
