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 has a 64-bit Python pre-installed unde default python location C:\Python27.  Therefore, we need to name our installation with another name, such as C:\Python27-win32.*

Here is the full list

h2. Important: Install Python under a custom named folder

*Talos has a 64-bit Python pre-installed unde default python location C:\Python27.  Therefore, we need to name our installation with another name, such as C:\Python27-win32.*

This is set during python installation.

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 as follows, rather than installed into python's site packages.
