Hello, I like the 'surface color ' feature in Chimera. I think, right now, the surface can be colored by radius, height, volume data and so on.. Is it also possible to color the surface based upon the NMR order parameters or intensity ratios (it will be an Excel file containing just two columns: residue numbers and the respective parameter values)? Or this can be done in some other way? Thanks in advance, Regards, Lalit Deshmukh, University of Connecticut Storrs, CT 06269
