• Data is extracted using the LCLS framework pyana or psana.
• GUI is implemented on PyQt,
• visualization of data uses matplotlib,
• data processing algorithms are accelerated by NumPy and SciPy libraries.

...

This tutorial follows to the Manual XTC Explorer - Old, shows how to set up environment, start xtcexplorer, explore content of the xtc file, interactively create/edit configuration file for pyana/psana, run it interactively and in the command line, etc.

Set up environment

• See for details Analysis Workbook. Account Setup
• Log onto any machine of the interactive pools psananeh (for AMO, XPP, SXR data) or psanafeh (for XCS, CXI, MEC data):

  Code Block
  ssh -Y pslogin ssh psananeh or ssh psanafeh

• Once per session execute one of the following scripts
  • for bash shell:

    Code Block
    . /reg/g/psdm/etc/sit_env.sh

  • or for csh shell:

    Code Block
    source /reg/g/psdm/etc/sit_env.csh

• You should always run this application from your own release working directory:

  Code Block
  newrel ana-current my_tutorial_release; cd my_tutorial_release; sit_setup;

  At this point you are ready to go.

...

These modules can be used in configuration file with parameters described in XTC Explorer - Old#The pyana modules.

What to use pyana or psana?

...

Framework interfaces in pyana and psana modules are slightly different, that is explained in
