Leginon

h1. FEI Talos installation specifics

h2. IMPORT NOTES

Because all interaction with the scope uses COM interface that is only accessible through 32-bit architecture, python running Leginon component is the 32-bit version.  Use the 32-bit Windows files (those marked as win32 and certainly not the ones says 64) in http://emg.nysbc.org/projects/leginon/files for these.

*Talos On-system UI uses 32-bit python as well*.  Therefore we just need to install the dependency that is missing in there.  The location of this python is

<pre>

C:\Tecnai\OnSystemUI\Python27

</pre>

Here is the full list

{{include(Windows 32 External Package Installers)}}

{{include(Comtypes_installer)}}

The rest of the installation is similar to other FEI systems.
