Dear guys, 

    Sorry to disturb you guys. When I use the UCSF ChimeraX, I try to define the second structure for part of model. I type the command like "dssp (#1 & sel) energy cutoff 0.5 minheliexlen 3", it works for the whole model instead of what I choose specially. Could you please help me? Thanks so much!

Best,
