[Chimera-users] Ligand Problem

[Marcus Fabiano A. Mendes]

Hi,
My Name is Marcus, and I am a huge fan of Chimera. Currently, I'm using Chimera to visualize p:MHC complex and it's electrostatic potential map. p:MHC occurs as an α chain composed of three domains - α1, α2, α3, β2 microglobulin and a ligand present in the groove. Chimera automatically recognizes the epitope as a ligand, since they have on average less than 10 amino acids. There's someway to make the Chimera don't recognizes this epitope as a ligand? A option to set the parameters that Chimera uses (ligand = <10 amino acids)?
Thanks for All
SincerelyMarcus Mendes
