Hi Hernando, Multiscale models assigns colors by chain by default. All copies of chain B will initially get the same color. All copies of chain C get another color. If you wish to change those colors, select a chain surface, click the select Copies button, then use the Color button or the Actions / Color menu (in Chimera 1.3 or newer). Maybe the case you are thinking of is where chains B and C are really copies of the same protein with different conformations. If you select the surface for chain B you can then select all chains which have identical amino acid sequences with shortcut xc, then color those. Now if you have several chains that are the same protein but have different sequences (maybe some residues not observed in some of the copies) then they are not identical. Then you'd just have to hand-select one copy of each chains known to be the same, press the Copies button and color. This is the situation with rice dwarf virus 1uf2. Might be nice to have the ability to extend selection to all chains that have the same chain name (given in PDB file though not currently used in Chimera). Tom hsosa@aecom.yu.edu wrote:
Is it possible to assign colors by chain to the surfaces created my the multiscale models tool ?
