Leginon

h1. 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:

<pre>

$PYTHONSITEPKG/leginon/cscheck.py

</pre>

On Windows:

<pre>

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

</pre>

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,

<pre>

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

</pre>

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:

<pre>

[tem]

class: fei.Tecnai

cs: 2.0e-3

</pre>

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

* pre 3.3 Leginon version should see in instruments.cfg scope class as tecnai.Tecnai
