Leginon

We have the same desire here - to close column valves remotely, and even from home, if you have left leginon running overnight. Right now the only way to close valves in leginon is from within the Instrument node, which is running on the tecnai client, so this doesn't help if you want to do it remotely. The method most people here use it by running a VNC viewer to gain remote access to the tecnai desktop. We have even used this to shutdown leginon from home and close the valves.

I think the true solution here is that we will make a new TEM control node that runs remotely from the Instrument node but has many of the same controls. There is a slight chance this will show up in the soon to be released version1.1.

Is there any information/ documentation about writing Python scripts that use pyScope? (By the way, did pyScope replace emscope?) At present we do not have anybody handy to top the liquid nitrogen up round the clock; but it would be nice to be able to shut things down properly when they are unattended. We are interested in having something that would shut down Leginon, close the column valves and then start the cryo cycle. (I think that is what is needed so the microscope can then be left unattended, without topping up liquid nitrogen, for a while?) This might be done in a Python script that would use pyScope (and possibly the script would be started at the correct time with 'at'). Although ideally this would be done in a node I suppose. I can't find documentation for pyScope and I don't think the old emscope supported starting the cryo cycle anyway. FEI have offered to send us some Tecnai scripting to do this (except for shutting down Leginon). This would be a less neat solution than a Python script using pyScope (or a Leginon node) because it would probably mean running their script on the Tecnai PC to close the column valves and start the cryo cycle and my own script to shut down Leginon on the Leginon laptop (and somehow ensuring the two things are synchronised correctly - possibly just using the GMT time on the clock on each system),
