Leginon

h1. FEI Talos installation specifics

h2. Install win32 version of python subpackages

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_Common)}}

{{include(Comtypes_installer)}}

*If the system comes pre-installed with 64-bit python as well, some of these packages may get confused.*

During these installations, keep an eyer on where the packages are installed into.  If it attempts to install into the 64-bit python at C:\Python27, contact Leginon Team through Forum.

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

h2. (Strongly recommended) Use local myami folder to run Leginon

Because we install into FEI's framework folder, it may be erased at the next upgrade by the service engineer.  To reduce the possibility of loss of local modification, we recommend using local myami checked out from NRAMM svn repository directly, rather than installed into python's site packages.
