[Chimera-users] How to lower the map size

If you set the “step” value to 2 (above the histogram in the volume viewer dialog) then Chimera uses every other grid point along the 3 axes (8 times less data). If you really want to produce a binned map (e.g. averaging 2x2x2 grid points to make a map half the size in each dimension), then use the Volume Filter dialog (menu Tools / Volume Data / Volume Filter) or the “vop bin” command, then save the resulting map to a new file (Volume Viewer dialog menu File / Save Map As…).
