<div>Dear Alex,</div>
<div>
<div><br>
</div>
<div>Instead of calling chimera from a python script, you can simply use chimera's python to run the script and call the command line commands with the runCommand() function. This way, you can have just the python script and avoid the cmd dependency.</div>
<div><br>
</div>
<div>You can run the following script with "chimera --nogui script.py":</div>
<div><br>
</div>
<div>"""</div>
<div>
<div>import chimera</div>
<div>from chimera import runCommand as rc</div>
<div>rc('open 1BPT')</div>
<div>rc('swapaa tyr :5; swapaa phe :7')</div>
</div>
<div>"""</div>

<div>Thank you both for your answers! <br>
Eric I am not trying all rotamers, I just want to have some specific rotamers in the binding sites of my protein-DNA models. I am using a python script to call chimera and a cmd script with all the swapaa commands that I need. Is there another way?<br>

Also, the "lib" keyword to the swapaa command allows you to pick the library to use, e.g.: swapaa ASP :41.a lib dynameomics criteria 2<br>

out how many rotamers are available, which isn't really possible with just the swapaa command.<br>
