In order to work with data on shared memory one has to be on specific monitoring node which is set in sxperiment sxr experiment configuration file. Currently for sxr it monitoring node is daq-sxr-mon06. It can be accessed through the chain of nodes (depending on where you are now):

ssh -Y [<user-login-name>@]psdev
e.g.-> dubrovin@psdev7a

ssh -Y [<user-login-name>@]sxr-daq
e.g.-> dubrovin@sxr-daq

ssh -Y [<user-login-name>@]daq-sxr-mon06
e.g.-> dubrovin@daq-sxr-mon06

Make sure that your login name have a permission to see xtc and calib data for your experiment, e.g.

...

source /reg/g/psdm/bin/conda_setup
source conda_setup --reldir /reg/neh/home/dubrovin/LCLS/con-ana-1.2.12-emon

First command sets regular psana-conda environment.  Second command is required in current development mode touse updated version of code.

Run application

cd <any-directory> # application saves/reads a file with configuration parameters in local directory (should have write permission)
emon

Main control window started from scratch and with configured fields:

Set application configuration parameters in main GUI

• Exp:Select ->
• Run -> 2
• Ext -> shmem ### make sure that daq is running or use None to load data from xtc file
• Select one of three monitor tabs, e.g. Mon-A
  • Det1: -> GMD, WF or Area -> View -> scroll/drug for signal, set ROI Signal; scroll/drug for background, set ROI Background,
  • Det2: -> GMD, WF or Area -> View -> ...
• Select one of three monitor tabs, e.g. Mon-B
  • Det1: ->...
  • Det2: ->...

• Events update (type in (int) number ~100 or 200)

• Start

...

Saved files

At exit emon saves a couple of useful files with configuration parameters and session log-file:

./emon-confpars.txt - saves non-default configuration parameters after session
/reg/g/psdm/logs/emon/2017/06/<log-file>.txt 

What if something does not work?

This is a new app, so it is not perfect and some glitches are very possible. Many protections for different situation are included, but most likely not all. Below is a most probable list of problems with recommendations what to do if it happens.
