[Chimera-users] Centroid/axis question

[Elaine Meng]

Hi Luca,
Unfortunately there is no friendly way to do it, but you could try saving the session and then editing the python in the session file (very carefully).

According to Eric, you would open the session file in a text editor and search for AxisManager, which will be followed by lots of comma-separated values in parentheses.  For each axis there are two numbers, then axis name, then a zero, and then the radius value, and then more numbers for other stuff like color and length.  I guess you can look for the axis name and then the zero, and then edit the next value for each axis.  I tried this and it works, but it is somewhat difficult because there are so many values all on one line in the file. 

Sorry it is not a friendly approach.  Depending on how you made the axes, it might be easier to script making them again than to manually edit the session.  I hope this helps,
Elaine

Is there a way to do this for an existing axis/centroid, or do I need to create them again? I have got quite a lot of them…
