h1. Configure leginon.cfg

For older versions of Appion and Leginon (pre-2.2), please use the following instructions:

[[configure_leginoncfg_2_1|Instructions for Appion and Leginon versions prior to 2.2]]

h2. The order in which Leginon/Appion looks for leginon.cfg

# individual user home directory

# $PYTHONSITEPKG/leginon

 

Note: You can discover the $PYTHONSITEPKG path by starting python:

<pre>

python

import sys

sys.path

</pre>

The first path to site-packages should hold the config file.

 

# /etc/myami (on Unix)

h2. Locate the search directories and the currently loaded cfg files by running the following python script in $PYTHONSITEPKG/leginon

<pre>

configcheck.py

</pre>

h2. Configuration file template

A skeleton (default) configuration file is available:

<pre>

/path/to/myami/leginon/leginon.cfg.template

</pre>

h2. Create a global leginon.cfg

Copy leginon.cfg.template to leginon.cfg.

<pre>

sudo cp -v /path/to/myami/leginon/leginon.cfg.template /etc/myami/leginon.cfg

</pre>

Edit the newly created file and add a directory for images. Make sure you have permission to save files at this location. See [[File Server Setup Considerations|File Server Setup Considerations]] for more details

You may put in a fake path on the microscope PC installation and ignore the error message at the start of Leginon if you follow our general rule of not saving any image directly from  the microscope pc,

<pre>

[Images]

path: /your_storage_disk_path/leginon

</pre>
