Test Case #1272
openTitan software upgrade
0%
Description
I am starting a thread about my observations after upgrading to Titan 1.2.0.5690. This also required an upgrade to Gatan GMS 1.83.842. Wim Hagen, an FEI applications engineer tells me this also applies for the upgrades to Tecnai 4.x
Here are some of my observations:
TIA is now required for camera embedding through the TEM UI
DM can still be used separately without embedding
My preliminary observations are that Leginon works better if TIA is NOT open. I should note that I only made one attempt to figure this out.
I will add more as I come across differences in behavior.

I don't know if it has to do with the DM and Titan software upgrade or the trunk version of leginon, but every time I try to take an image, it will withdraw the camera and reinsert it before taking the image. I do not have this problem with the release of Leg 2.1.

We have some new code in the trunk that helps to deal with having multiple cameras used in the same session. You can set up to use one camera on a preset and then use a different camera on another preset. When an image is acquired, it has to retract any cameras that are above the one that is being used. You are not using multiple cameras like this, but I think Leginon is confused because you are using more than one method to access the same camera (Gatan and TIA). This is my guess, so let me know if I am wrong. If you edit your instruments.cfg to have only Gatan or TIA but not both, then it will not think it has to retract one of them.

In the previous Titan version, I had to do the procedure here [[http://emg.nysbc.org/projects/leginon/wiki/TEM_Scripting_Beam_Tilt_Calibration]], and I made the rotation_center_scale 6.4. In the newest Titan version, I had to change it back to 1.0

With the previous version, I was unable to calibrate beam shift; now I can.
