Hi, I write in this mail to ask your great help on the slicing of MRC files. I want to slice a map in MRC format in half and save it as a new MRC file which only contains the remaining half map. However, it seems that the "Per-Model Clipping" function of Chimera can only work on the visualization mode, without connection to the "Save map as" function to attain a new map file. I am wodering if there is any other method to realize my intention. Thank you very much! Sincerely yours, Jian

Hi Jian, You are right that "Save map as..." ignores the per-model clip planes and near/far clip planes. The clip planes only effect what is displayed, not what is saved. To save a rectangular region of a map that may not be aligned with axes of the original map you need to interpolate the map on a new grid. The procedure for doing it is described in the Guide to Volume Data Display: http://www.cgl.ucsf.edu/chimera/tutorials/volumetour/volumetour.html#resampl... Tom
