Hello,

I noticed that there was an article about QwikMD which makes running the NAMD simulations easier, complex, and efficient.

But I have a problem. I'm just doing the basic example where I have to rename a protein, and I have to import the topology file to rename the the atoms in the protein, basically C becomes C1, so forth.

But the issue is that permission is denied in /usr/local/lib/ ...

Error:

"couldn't open "/usr/local/lib/vmd/plugins/noarch/tcl/readcharmmtop1.2/top_all36_cgenff.rtf": permission denied

couldn't open "/usr/local/lib/vmd/plugins/noarch/tcl/readcharmmtop1.2/top_all36_cgenff.rtf": permission denied"

Normally if I have an issue with permission denied, I run the program as root in linux or just sudo. But I can't launch vmd as root. Then again, this error doesn't make any sense because I installed vmd in a subfolder of /usr/local/lib which is the same place where I can't open the vmd topology files to edit!?

What do you think I should do?

I appreciate your help with this troubleshooting.
