Hi,
I want to find deuterium order parameter of the system of
DPPC+SM+CHOL+WATER
g_order -f traj.trr -s topol.tpr -n index.ndx -dt 0.001
it gives the following error:
Taking z axis as normal to the membrane
Reading file topol.tpr, VERSION 3.3.3 (single precision)
Using following groups:
Groupname: System First atomname: C1 First atomnr 0
Groupname: DPP First atomname: C1 First atomnr 0
Groupname: SM First atomname: C1 First atomnr 1000
Groupname: CHOL First atomname: C1 First atomnr 2000
Groupname: SOL First atomname: OW First atomnr 2580
trn version: GMX_trn_file (single precision)
Reading frame 0 time 0.000 Number of elements in first group:
3180
-------------------------------------------------------
Program g_order, VERSION 3.3.3
Source code file: gmx_order.c, line: 360
Fatal error:
grp 1 does not have same number of elements as grp 1
-------------------------------------------------------
How can I analyze the order parameter my system? Can you answer my
question?
I don't understand what to do.
Regards,
Anirban
