Combining 2 electron density maps in 1
Hi, I would like to open two electron density maps in chimera and save/merge them together in one map. Both maps are activated in the "model panel" but I cannot select/save both at a time using the volume viewer. I appreciate your help! Kind regards Mazdak
Hi Mazdak, As mentioned recently by Tom Goddard, currently there is no way to save two maps in one file: http://www.cgl.ucsf.edu/pipermail/chimera-users/2007-February/ 001350.html Elaine ----- Elaine C.

Hi Mazdak, Chimera cannot currently merge two maps into a single map. It can only save a single map and allows writing just a zone or a subregion or a hand-erased modifications, and allows a new origin, grid spacing, and file format. We would like to add the ability to merge maps. Could you explain your case? Do the two maps overlap each other? How would they be combined if they overlap (added)? Are the grids of the two maps aligned so that all grid points of both data sets are part of the same bigger grid? Or would the data need to be interpolated at new grid points to make a merged map? I have written a script that stacks two copies of a map on top of each other and writes a single new map for making filaments twice as long where the original map contains a single periodic repeat.
