[gmx-users] g_dist

[dina dusti]

Dear Prof.

Thank you very much from your response.
Yes, I contacted with one of them and she said me use g_dist, but I have problem with it.

Thank you again because of your patient.
Best Regards
Dina

It's hard for anyone to speculate about an article that we haven't read.  The best course of action is to contact the corresponding author and ask for additional information.  Based on what you learn there, you can apply similar analyses.
