Hello, I'm new to Chimera, but would like to use it to generate surface maps of electrostatic potential and hydrophobicity, then output for further analysis. I've generated maps using coulombic and mlp commands, and successfully saved these to .MRC format. However, when I go and read these files, the dimensions of the maps are different, so I'm not sure how to properly overlay these maps in my later analysis. Is there a way to have Chimera generate maps only within a given spatial range, so I end up with maps of the same size? Or another way you would recommend going about this? In later analysis I'd also like to make use of the SAS calculated by Chimera, and I imagine I will also have difficulties properly aligning the surface to the maps, so any advice on this would also be greatly appreciated! Thanks, Megan Steves
