[Chimera-users] question about measuring volume via command line and the nogui option

Hi Bruno,

  There is no Chimera command to report volume enclosed in a surface, so 
I've added one.  Example

    chimera --nogui --nostatus
    > open 1a0m
    > surf #0
    > measure volume #0
    MSMS main surface of 1a0m:  volume = 3212.8
    > measure area #0
    MSMS main surface of 1a0m:  area = 1887.7

It will be in tonight's Chimera daily builds if they succeed.  Note the 
use of --nostatus on the Chimera command-line to suppress the extra 
messages.  Many Chimera functions are only available in Python scripts 
and we recommend using Python if you run into cases where Chimera 
commands are lacking.
