• Configure transition

• BeginCalibCycle transition
• Enable transition
• L1Accept transition — This is the event data. Each event starts with "L1Accept transition:". From the text that follows, you can get an idea of what detector data is in the xtc file.

A new tool to list the contents of the file:

pslogin ~ >  xtcsummary.py 

lists all detector and epics information found in Configure and L1Accept (event data) sections, and lists number of events per calibration cycle. Can be helpful when putting together your myana or pyana analysis script. Example output.

You can analyze the xtc data with the offline tools, myana and pyana. You also have the option of using the hdf5 data format (hierarchical data format 5), but you will have to wait for the xtc -> hdf5 translation which may take some time. Also, there is no support for hdf5 analysis by the offline group quite yet. hdf5 will be the standard offline LCLS data format, and tools are under development for analyzing these files. More about data formats and where to find the experiment data files, see Analysis Workbook. Data Formats
