h1. Start Leginon at your main working station remotely

# [[Set up for a new regular user|Set yourself up as a Leginon/Appion user]]

 

# Start the remote Leginon Client on the microscope

 

[[Run Leginon Client on the Microscope Computer|Start the remote Leginon Client on the microscope]] as described in the previous section if you have not done so. For Tietz camera, this will need to be restarted every time you establish and then remove the connection to it.

 

# Start the main Leginon processing program

 

**  start-leginon.py (From any directory for Linux)

Note: This works because start-leginon.py is installed in the default bin path and the rest of the python files in python's default site-package directory.  If you other modules in the python path, there is a possibility that a wrong module is loaded as found in http://emg.nysbc.org/boards/6/topics/788.  Reset the python path before starting will solve the problem.

** "Connect to clients" should list the client host(s) you have just edited. If it says "(no clients selected)", you need to go back to the last step and make sure you click on "+" after you make each host you want appear in the selection window.
