Hi Elaine,

   thank you very much! I should have mentioned that I have just a 
volume no coordinates. I checked Atom Box but it just allows one to draw 
the box around selected atoms but not around a marker. At least I could 
not find any option for that. I have set a marker on the volume and want 
to cut out a box with its center on the marker.

Best, Dieter

Then use Volume Viewer menu Features… Data display options, "show outline box..." on the cropped data set.  You can move the slider so that no isosurface is shown for the map.  However, the box size is specified in units of distance (generally Angstroms) not pixels, and the original map must already enclose that whole volume.  I’m also not certain about whether the box would be EXACTLY centered on the marker… it might be slightly off due to rounding and grid-spacing of the original map.
