There is no Chimera command to measure surface area or surface-
enclosed volume, but there are keyboard shortcuts (Accelerators) to
perform these measurements on the currently selected surface(s).
(1) turn on Accelerators (Tools... General Controls... Accelerators On)
(2) select the surface(s)
- for many kinds of surface (molecular, multiscale, etc.), simply
use Ctrl-click to select, Shift-Ctrl-click to add to selection
- the only way I was able to select a volume surface for these
measurements was to use the Model Panel (under Favorites): choose the
volume surface on the left side of the Model Panel, click the
"select" button on the right
(3) type the accelerator "ma" to measure area and "mv" to measure volume
For details, see:
However, accelerators cannot be included in a Chimera command script,
and you would still have to select the surface(s) interactively.
In the future we hope to have the surface calculations more
integrated and available with Chimera commands, but it has not been
I hope this helps,
