h1. How to Update from v22 to 3.0 (Instrument Windows Computer)

The changes to v3.0 DOES require upgrade at the microscope and camera computers.

We have compiled all pre-compiled installer with python 2.7 now.  Therefore, you do best by following the [[Installation_on_the_instrument_computers|complete installation instruction]] until you reach the part for configuration.

See [[Installation Troubleshooting]] and  "Leginon Bulletin Board":http://emg.nysbc.org/projects/leginon/boards  searching

for "install" if you run into problems.

h2. copy the old config files to the new location.

*If you want to avoid copying cfg files to new installation in the future, copy them from where you had it in the python2.5 2.2 installation to the global config directory*

{{include(locate global config directory on Windows)}}

|_config file_|likely location in 2.2 installation if not in your home directory|

|sinedon.cfg|C:\\python25\Lib\site-packages\sinedon\|

|leginon.cfg|C:\\python25\Lib\site-packages\leginon\config\|

|instruments.cfg|C:\\python25\Lib\site-packages\pyscope\|

h2. modify Tietz PXL camera imaging size if you did so before for Leginon 2.2

*You should not copy the old one in this case since the file has been changed*

*  Go to C:\Python27\Lib\site-packages\pyscope\

*  Edit tietz.py with a plain text editor

*  Find the lines:

<pre> def getCameraSize(self):

# {'type': dict, 'values': {'x': {'type': int}, 'y': {'type': int}}}}

x = self._getParameterValue('cpTotalDimensionX')

y = self._getParameterValue('cpTotalDimensionY')

return {'x': x, 'y': y}

</pre>

*  Change the last line to:

<pre>    return {'x': 2048, 'y': 2048}</pre>

h2. About [[TEM Scripting Beam Tilt Calibration]]

* If you have done [[TEM_Scripting Beam Tilt Calibration]] and have changed the scale factor in tecnai.py, you should copy the value to your new installation.
