Hi Chimera developer,

I encounter a problem with surface calculation/display when using the biological assembly (dimer) of 1Q90. The monomer on its own, as in pdb file 1Q90, displays the surface with no problem. I have tried the “split” command without success on the biological assembly. Also tried changing parameters to no effect. Would you please help.

Regards,

Sujith
