[chimerax-users] Saving ChimeraX log, saving protein sequence to file

[Elaine Meng]

Hi Prathvi,
These answers are both for ChimeraX so I CC'd the chimerax-users list.

(1) ChimeraX command "log save" saves it as HTML 
<https://rbvi.ucsf.edu/chimerax/docs/user/commands/log.html>

(2) in ChimeraX, open the structure, show the sequence of the chain of interest (menu: Tools... Sequence... Show Sequence Viewer, choose chain if there is more than one chain preset).  Showing the sequence can also be done with the ChimeraX "sequence chain" command. 
<https://rbvi.ucsf.edu/chimerax/docs/user/commands/sequence.html#chain>

 Then in the sequence viewer window, the context menu has a choice to save the contents (File... Save As...). 
<https://rbvi.ucsf.edu/chimerax/docs/user/tools/sequenceviewer.html#context>

You show a context menu in ChimeraX with Ctrl-click or right-click (depending on your system) in the tool window.
<https://rbvi.ucsf.edu/chimerax/docs/user/window.html#context-menu>

In Chimera, #2 is similar, use main tools menu to show sequence, use sequence-viewer tool's menu to save it to file.

I hope this helps,
Elaine
