[Chimera-users] Attribute "distance" generated by shortcut "ac sd" not saved between sessions?

[Oliver Clarke]

Hi all,

I use the command “ac sd” to color dotted surfaces such as the attached by pore radius (I generate a molmap surface corresponding to the channel axis and then use "ac sd" to generate an attribute “distance", which in this case corresponds to the pore radius, which I can then use to color the dotted surface pdb using Render by Attribute). 

The dotted surface is generated using the program HOLE (http://www.smartsci.uk/hole/) along with the attached script to make it readable by chimera.

This all works fine, however I have noted that the attribute generated by "ac sd” is not present when I reload the saved session, whereas other attributes (e.g. those created explicitly with defattr) are. 

I can just regenerate it of course, but it would be convenient if it were saved with the session, as it can take a while (~10 minutes) to calculate for large dotted surfaces.

Cheers,
Oliver.
