[gmx-users] gmxdump to check the position restraints

[Jian Zou]

Hi all,

I was told position restraints could be checked using "gmxdump -s 
topol.tpr", and search for POSRES

I did so to my .tpr file, as follows
functype[225]=POSRES, pos0A=( 2.70400000e+00, 2.25000000e+00, 
5.15799999e+00), fcA=( 1.00000000e+03, 1.00000000e+03, 1.0
0000000e+03), pos0B=( 2.70400000e+00, 2.25000000e+00, 5.15799999e+00), 
fcB=( 1.00000000e+03, 1.00000000e+03, 1.00000000e+03)

How could I know which atom the function POSRES is applied to? based on the 
position vector? Is there some correspondence between the number following 
"functype" and the atom number in the .gro?

Thanks in advance.
