I'd like to use protein structure data from PDBs visualized by Chimera to do two things. I'd be happy to learn the appropriate tools and methods.
・Mapping information about amino acids present on protein surfaces to sequences
・Find the charges of exposed amino acids on the surface and apply color gradations to the amino acid molecules according to their values
The second one in particular looks like it could be done with Chimera's "Coulomb surface coloring". But I'm not sure what kind of value to enter underneath the color and how to find it, which is needed to add a gradient.
Sorry for my bad English ...
