Dear Takeshi, For a PDB fitted to a map, just use "File... Save PDB" in the menu and make sure to choose the option to "save relative to" the map model. For saving a map fitted to another map, you could just save the Chimera session, which will preserve the orientations of the different models. However, if you want to save a map file to use in other programs, it is necessary to resample the map that you fit on the grid of the map you fit into. Resampling interpolates data values and can degrade map quality. You can create a resampled map with the "vop" command and then save that new map with the Volume Viewer dialog or "volume" command, as described in this previous post: <http://www.cgl.ucsf.edu/pipermail/chimera-users/2008-January/ 002238.html> More about "vop": <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html> I hope this helps, Elaine ----- Elaine C.

Dear chimera developer I want to save fitted map after using "Tools/Volume Data/Fit in Map" as MRC file. How can I do this? Is there the same kind of function when we save fitted PDB file related to Map. Thank you in advance, Takeshi
