<div dir="ltr">I am trying to make a radial temperature profile of a given thickness. I originally used the confout.gro file containing the final output of velocity and position of each atom to calculate the temperature from the velocity but would like to take time averages now.<br>

<p>AS> The system works now, thanks for finding a simple mistake. Another question I had is if I want to calculate the average velocities of all the atoms over a period of time can I use g_traj to create an average velocity of the atoms, but looking at all_veloc.xvg file the atom number starts at 0 so I don't know where to cross reference it with another file to coordinates of that atom. Is there a function in GROMACS that will give averages of velocities and positions of atoms?</p>

<p>I think you can find the average atom velocity from of temperature of the system. Telling the truth I don't know why you want ones. If you tell the final result you need probably I can be of more use.</p>
<p><br></p>
<p>I don't really remember from what number the atoms numbering starts in the programme you speak about but if it starts from zero this corresponds to the first atom in your conf.gro.</p>
