        <span style="font-family:SimSun;">Hi,</span>
</p>
<p>
        <span style="font-family:SimSun;">I've tried to use chimera nogui mode to save chimera sessions for a large number of tasks (one session for each task). However, an error message was returned and without the wanted output.py being written. The command I used is <span style="background-color:#CCCCCC;"><em>chimera --nogui --silent run.cmd. </em><span style="background-color:#FFFFFF;">( followed this https://www.cgl.ucsf.edu/pipermail/chimera-users/2011-October/006863.html​)</span></span></span>​
