This page describes smalldata_tools, a suite of code useful for analysis from the xtc data to small(er) hdf5 files at several stages of analysis. While this page is written with smalldata_tools usage in mind, the information here are also of interest to understand the computing infrastructure, ressources and directory structure.

The smalldatat_tools code can be found on git at at https://github.com/slac-lcls/smalldata_tools.

At XPP or XCS, the code setup is usually taken care off by the beam line staff. For other hutches, please contact the controls POC or pcds-poc-l. The working directory generally are:

/cds/data/psdm/<hutch>/<expname>/results/smalldata_tools 

for the offline system (psana) and

/cds/data/drpsrcf/<hutch>/<expname>/scratch/smalldata_tools 

for the (new) fast feedback system (psffb).

Online and offline analysis

...

The results folder should hosts most of users' code, notebooks, etc. This folder lives on the offline system but is mounted on the ffb:

/cds/data/psdm/<hutch>/<experiment>/results/.

The smalldata_tools working directory generally are:
