You can color a cryoEM map surface #2 directly using coulombic #1 surface #2 and also mlp should work mlp #1 surface #2 but the mlp command has a bug that prevents that from working -- I will fix it next week. Tom

Hi
I tried looking up on colouring atoms by hydrophobicity/ electrostatic potential, but couldn't find a way to work in my current model. So, please excuse me if this is redundant.
I am working with a pdb: 6j5k and was thinking of a way to color the atoms by hydrophobicity. From this, the idea is to also use this atomic model to color a map (a cryoEM map MRC format) based on hydrophobicity, using the command 'color zone'.
First, I tried to generate a 'mlp' using the command:
mlp #1 map true color true
Even after saving the volumes in .mrc format, I am not sure how to load them up to 'color the atoms by hydrophobicity'; the command 'color sample' only seems to accept the surfaces for colouring. I also looked up coloring by attribute - but the hydrophobicity/ electrostatic doesn't seem to be a part of it.
Also, there are lots of subunits/ chains, so is there a more straightforward way to load these hydrophobic-potential-maps later and color the atoms by hydrophobicity? In this particular case, I am trying to color the 'whole' pdb model and the cryo-EM map by hydrophobicity EMD-0667 <https://www.emdataresource.org/EMD-0667>.
Any workaround suggestions would be helpful for electrostatic too.
