Hi Elaine, sorry, but I still do not understand the syntax. I am trying to make a box around marker 1 within marker set 1. I tried "vop boxes #1 marker 1 isize 50" but this does not work. I have to give an atom definition of one of the markers in marker set #1. If I mouse over it it tells the name: "#1 marker 1" whereas its name in ModelPanel is "marker set 1". How do I translate this in an "atom specification"? Furthermore, it does not recognize "isize" but this might be due to an error earlier in the command! Can you please give me an example of the command! Thanks again, best wishes, Dieter ------------------------------------------------------------------------ Dieter Blaas, Max F.

Hi Dieter, There is a command-line option to avoid this problem. See the “vop boxes” command with the “isize” option (instead of “size”): <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#boxes>
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Dear all and Elaine,
I have an mrc volume of 450 x 450 x 450 px, put a marker at a particular location and cut out a box with 'Box around selected atoms with padding 60'. However, Chimera shows me the boxed volume as 124 x 123 x 124. I understand that the higher value must result from the voxel size being 0.97 A/px, so the dimensions would be 123.71 x 123.71 x 123.71 or anything similarly rounded. BUT why are the dimensions in x,y,z different and the box not exactly cubic? I noticed that it might have to do with centering but I do not understand how I can cut out a 'really' cubic box!
Thanks for help, best, Dieter
