Dear all,<br> I am having a problem in running some post analysis commands like g_rdf on my computer . When my simulation is complete I type in the following command to calculate the radial distribution function for the system " g_rdf -f
traj.trr -s topol.tpr -o rdf.xvg -b 0 -e 20 " and the program gives a message like this <br><br><br>:-) G R O M A C S (-:<br><br> Gallium Rubidium Oxygen Manganese Argon Carbon Silicon<br><br> :-) VERSION

I checked for the installation of g_rdf and found it to be installed . My simulation was completed and for command like "trjconv" can read all the frames . Then why is "g_rdf" command failing to read all the frames?
