[gmx-users] How to Calculate tetrahedral order parameter

[Soham Sarkar]

Dear all,
        I know this question was asked by many users before but searching
them all I did not get how to perform it in GROMACS. Please help me with
this. Is there any in built command line exist for Tetrahedral order
parameter calculation? If gmx hydorder is the existing tool for calculating
tetrahedral order parameter, went through this I did not understand the
usage of it too.
Thanks in advance-
Soham
