Friends,<br><br>I loaded a amber trajectory in chimera. I simply want to calculate the distance between two atom in each frame in the traj. and write it to a text file. I used the per-frame utility in MD movie tool. <br><br>
I chose interpret script as &#39;chimera commands&#39;<br>substitute text 001-200 (frame 1 to 200)<br><br>In the script section i gave<br>distance :163@CA :166@CA<br><br>It reports to me the following in the reply log.<br>
Distance between GLY 163 CA and ARG 166 CA: 5.083<br>Problem in per-frame script:<br>Distance monitor already exists<br>Problem in per-frame script:<br>Distance monitor already exists<br>Problem in per-frame script:<br>Distance monitor already exists<br>
<br>How should i actually use the perframe option so that the analysis will be done in each frame and reported output file will hve the distance values for every frame.<br><br>Thanks,<br>Bala<br><br><br><br> <br>
