The command "cxi.pyana" can be configured to display the diffraction images streamed from an XTC file.

== Configuring the viewer ==
Add to the mod_view section of your pyana config file as follows:
<pre>
[pyana]
modules = my_ana_pkg.mod_view
num-cpu = 1

[my_ana_pkg.mod_view]
address = CxiDs1-0|Cspad-0
calib_dir = /reg/g/cctbx/sources/cctbx_project/xfel/metrology/CSPad/run4/CxiDs1.0_Cspad.0
dark_path = /reg/d/psdm/cxi/cxib9713/res/darks/r0001-Ds1-avg.pickle
dark_stddev = /reg/d/psdm/cxi/cxib9713/res/darks/r0001-Ds1-stddev.pickle
detz_offset = 555

# Suitable values depend on the repetition rate of the instrument.
n_update = 120
n_collate = 60
</pre>

The command is run as follows:
<pre>
cxi.pyana -c myconfig_file.cfg /path/to/xtc/streams/e346-r0007-s0[0-4]-c00.xtc
</pre>
The command will marshal together all events from streams 0-4 in run 7 of experiment 346. Those events with the CXI imaging detector with the given <code>address</code> will be sent to the <code>mod_view</code> module that displays images in a GUI. Dark subtraction is done with the files <code>dark_path</code> and <code>dark_stddev</code> that are described on the [[Preparatory steps]] wiki page.
Important parameters are:
* <code>n_update</code>: GUI will only display every Nth event (every 120th image, in this example).
* <code>n_collate</code>: GUI will display an average image over the last N events (last 60 events, in this example).
'''Critical step:'''
'''Please press the Run/Pause (green) button in the GUI to make the action start.'''
