this is the screen ouput of the gmx check
# Atoms 61151

Reading file md_0_1.tpr, VERSION 5.1 (single precision)
and tex file gives
A system of 18620 molecules (61151 atoms) was simulated.
A total of 100 ns were simulated with a time step of 2 fs.
Neighbor searching was performed every 10 steps.
The PME algorithm was used for electrostatic interactions.
with a cut-off of 1.4 nm.
A reciprocal grid of 64 x 64 x 64 cells was used with 4th order B-spline
A single cut-off of 1.4 was used for Van der Waals interactions.
Temperature coupling was done with the V-rescale algorithm.
Pressure coupling was done with the Parrinello-Rahman algorithm.
grompp is shows it will roughly generate 300MB!
i was suppressing the .trr file now with trr file it shows around 14GB
thanks you very much for your advice!!
