[Chimera-users] one question about slicing

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
