Shows how to fit 3 proteins in a map avoiding clashes between the proteins. This uses the fitmap command to fit each protein in turn after subtracting the density corresponding to the other two proteins. The demonstration uses a kinesin decorated microtubule EMDB 5027, protofilament alpha and beta tubulin PDB 1jff, kinesin motor domain PDB 1v8k, and decorating tubulin dimers PDB 1sa0.
