Hello I have low-resolution (~15A) model of decorated F-actin. I want to localize the "decoration" element by subtracting normal F-actin model obtained from Cryo-EM (EMD-5168) from my decorated model. The problem is that EMD-5168 has a higher resolution and "vop" command did not work. Even if it would work, it would be difficult to interpret the result of such subtraction. I think, both maps should be at approximately the same resolution. I know how to create low-resolution map from PDB, but I could not find any solution how to lower the resolution of the EMD-5168.map Any help would be greatly appreciated. Many thanks in advance.
