question about cartoon style strand xsection
Hi, I want to modify the width of beta strands, so I use the command: car style strand xsection rect width 1 and it works very well. Now I want to modify only certain strands, so I use: car style strand xsection rect width 1 car style #2-10 strand xsection rect width 0.1 for the later command, I get the error "expected a keyword". But, when I use the same type of command for helices it works well: cartoon style #2-10 width 0.1 thick 0.1 Is there something I'm doing wrong in the script or it is not possible for strands? Thank you for your help.

Hi Vincent, The atomspec in your command is slightly wrong -- probably you meant to intersect #2-10 with strand, for example: car style #2-10 & strand xsection rect width 0.1 You could also use parentheses around the atomspec in the command if that makes it clearer, e.g. car style (#2-10 & strand) xsection rect width 0.1 <https://rbvi.ucsf.edu/chimerax/docs/user/commands/cartoon.html#style> <https://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html#combinations> I hope this helps, Elaine ----- Elaine C.
