Hi, I had to resort to using grasp surfaces because MSMS doesn't behave "nicely" when dealing with multiple free floating residues that come directly from a PDB file. Although grasp surfaces are lower in visual quality than MSMS, grasp rendered all the areas I wanted whereas the MSMS plugin could not. So, after I did save session and re-opened the session the grasp surfaces did not reappear. Is there anyway to add functionality so that the grasp surfaces, colors, and the corresponding locations can be recalled when I load the saved session file? This saves time especially when there are many grasp surface components each with different colors. One more minor detail/UI glitch I noticed?: Color Editor -> click opacity : the "A" row along with slider appears -> unclick opacity : the sliders disappear but the "A" along with row space remains ...don't know if that was done on purpose. Thanks for the great program!
