Data file quality check

Datagram and XTC structure check

Assumes the loop over all Drgams in a single XTC file with iteration over all XTC containers.

Accumulate statistics for transitions

Accumulate statistics for damages

Check correctness of the datagram time sequence

Check consistency of size of external and internal XTC containers

Accumulate statistics for data types

Indexing?

The same procedure can be used for XTC data indexing..., but need to read all files for streams and chunks within run using the same algorithm like in psana.

Data quality check

psana-based analysis for selected types of data

Command line interface

b. xtcqc -f <file-name>.xtc

Database for XTC Quality Check

Whenever the xtc file is processed, the results are saved in the database

 
/reg/d/psdm/<INSTRUMENT>/<experiment>/xtcqc/<xtc-like-file-name>.qc

Web-based control and access

Igor is going to produce web-based interface, like for translator, with functionality as follows.

• Show list of files with processed/not-processed flag,
• Control on job submission for quality check,
• Browser for QC results of particular file/run.
