Check Cs value match before using Leginon after update¶

Run the following script on any of the computer where you have done the update on.

On Linux:

$PYTHONSITEPKG/leginon/cscheck.py

On Windows:

C://Python25/Lib/site-packages/leginon/cscheck.py

You should get a list of microscope where you have saved images on in a Leginon session and the Cs values that you entered using schema-r15653.py. For example,

TEM tecnai1234.Tecnai used in session 12jun07a has Cs value of 2.000e-03 m

Check that against the Cs value in instruments.cfg on the named microscope (tecnai1234 in this case) which is also listed in meters, like this:

[tem]
class: tecnai.Tecnai
cs: 2.0e-3
 

The two must match.  Otherwise Leginon will complain and you may lose all your old calibrations.
