Unlike Chimera's predecessor Midas, running Chimera in nogui mode
("chimera --nogui") doesn't expect or allow commands on standard input
(e.g. typing in the shell window). Instead, you use one or more file
name arguments on the "chimera --nogui" command line to have Chimera
execute the commands you want. When you say that "the program doesn't
start ", I'm guessing you ran "chimera --nogui" with no file name
arguments, which resulted in Chimera exiting since it had no files to
You can put normal Chimera commands in a file and have Chimera execute
those. Such files should either end in ".cmd" or ".com" or be prefixed
with "cmd:" or "com:" on the Chimera startup command line. So if you
have such a file named "make_alignment" with Chimera commands you want
executed then "chimera --nogui cmd:make_alignment" would execute it.
You can do the same with files of Python code, ending such files in
".py" or prefixing them with "python:".
As for MatchMaker, right now it is too closely tied to the GUI dialog
to be called from nogui mode. I will work on disassociating the
underlying computation from the graphical interface so that it can
become a command-line command. The hydrogen-bond finder has recently
been given this kind of treatment and is callable from the command line
in the release we will be making later this week. I'll send mail when
the same is true for MatchMaker.
It is possible to "remote control" MatchMaker in GUI mode, so that as
long as a window system is available, you could write scripts that
automate MatchMaker functions. They just can't be run in nogui mode.
But they can be run in an analogous manner to the above (e.g. "chimera
python:make_alignment") -- it's just that windows and so forth will pop
up until Chimera finishes. If you would want to do this, let me know
and I can send more details.
