[gmx-users] How can I calculate Potential Energy of the segment divided by index file?

[大木啓輔]

Dear Gromacs users 


I want to calculate Potential Energy of segment of the structure.
For example, segment that coordinations in z axis are 7.2 Å in the structure.

I could specify that segment of atom numbers by writing index file.
But gmx energy has no option of specifying segments by index file.

Then, how should I get the Potential Energy of segments?
Could you tell me how to solve this problem, please?

Sincerely.


Keisuke Ohki.
