I ran: pyscope.registry.getClasses() to see what was registered
and then realized the problem. The key is "Tietz SCX" (with a space) instead of "TietzSCX". This seems to be using the "name" attribute of the class (which we hard code in the class) rather than the name attribute, which would probably make more sense.
In any case, the temperature scripts have been written and tested. I moved them to the folder "Camera Scripts" on the desktop. There is the original one that just monitors the temperature, and two new scripts to warm the camera to 20 C and cool the camera to -25 C. You can change the exact temperature set point by editing the scripts. Although it seems the default cold point is -25 C, I was successful in setting it to -35 C. I got too scared to try anything lower, but it makes me wonder why we don't use something like -30 or lower if it could improve SNR. Not sure what the limit is, but must be some constant offset from the chilled water temperature. For now, just using the default -25 in the script.

How about Tecnai? The error message was different.
