FEI Talos installation specifics¶

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

C:\Tecnai\OnSystemUI\Python27
