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. Tom Bruno Villoutreix wrote:

Dear Chimera Users i am new to chimera, is it possible using something like: chimera --nogui open myfile.mol2

and then i would like to measure the area and volume...but i am not sure which command to use. I can get the surface with this command but to get the volume, i have to use the graphic interface, i do not see either the name of the command in the command history list...

thanks if you can give me some advices Bruno ------------------------------------------------------------------------
