Thank you Elaine! I played with it today and it looks great! Some additional questions (sorry for it at the first time the thing seems abit tricky): 1)may I automatically place the 2D label on the top left corner of the screen instead of manually defining its X-Y using xpos ypos? 2dlab create title text \"name_of_the_complex" color red font gothic xpos .04 ypos .99 size 40
You have to put the position in the command. The only other way is moving it by hand, which is probably not what you want to do.
2) assuming that I open 2 molecules in the same session open A.pdb open B.pdb then I remove all the models with the exemption of the first close #1.2-end How could I superimpose A to B (align the structures) and then hide cartoon from B.pdb (keeping only ligand) ?
See "matchmaker" command for aligning structures and "show" "hide" "cartoon" "surtace" commands for hiding and showing different types of display. There are many ways to specify certain atoms or models in a command (hide, show, cartoon, color, etc.): you can do it by model number, residue number, residue name, chemical element, etc. How to specify atoms in command line is explained in this page: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html> For example, ChimeraX commands: matchmaker #1 to #2 view ~cartoon #2 hide #2 & protein hide solvent
3) Is there any possibility to put your signature on the screen-shot? like "Observed by Enrico Martinez" ? :-)
Sure you can put whatever text you want on the image (titles, credits, arrows, ...) with the 2dlabels command.
Many thanks in advance!! Enrico
