Dear All,
 
I have a mrc file for a protein complex with a 3-fragment sheets (from A to B, from B to C, from C to D, and they were connected by H-bonds). Will you please  introduce to me on how to use color zone to split to get the mrc file for each fragment of the sheets? I have tried to do it by myself, however I find the splitting was not  done based on fragment, i.e., I cannot get the mrc file for each fragment of the sheets.

I am looking forward to getting your reply.

Smith
