Hello,
I am trying to calculate the Velocity Autocorrelation Function for my system using g_velacc. I have system of 128 ionic liquids (128 cations and 128 anions). I run the trajectory for 20 ns. I used following command . g_velacc -f 3.trr -n emi-etso4-127-no.ndx -s 3.tpr -o I selected "system" The output file, vac.xvg, have no data. Can any one tell why its not wirting.
