<DIV>Dear users,</DIV>
<DIV>As the Gromacs manual mentioned, "g_energy" cauld calculate the free energy difference with an ideal gas state. After a simulation of protein in water with GMX3.3.1, I have tried the following commands to compute deltaG.<BR> 1. g_energy -f md.edr -fee -fetemp 300 -o energy1.xvg<BR>2. g_energy -f md.edr -o energy2.xvg<BR>After the command line, I choose the item "potential". However, I have got idential xvg files with no info of deltaG.<BR>Could anyone tell how to carry out the deltaG computations?<BR>Many many thanks to you guys.</DIV>
