[gmx-users] about how to create angle.index with specific angles

[lazaro monteserin]

Dear gromacs users,

Is there any way to tell gmx mk_angndx to create the index file with
dihedral angles from a (.tpr) for specific atom numbers (atom level, e.g 1,
2, 3) from my molecule?

Any help would be very appreciate it.

Kindly,

Lazaro
