[Chimera-users] Creating a cubic box for a density map

Dear Chimera users When I use the Segment map option to save a specific fragment as .mrc file, Chimera uses the minimal box containing the segment. Does anyone know how to modify the dimensions of a density map to have it in a cubic box that can be used in Flex-EM?
