Overview

MRQART

MR Quality Assurance in (near) Real Time. See see static debug-enabled page for a demonstration. Full toolchain uses

1. Samba server receives files from scanner (iceconfig)

2. :py:func:`mrqart.main` initializes an inotify watcher

3. New dcm files parsed with :py:func:`dcmmeta2tsv.DicomTagReader.read_dicom_tags`

4. Headers compared to template :py:func:`template_checker.TemplateChecker.check_header`

5. Dicom vs template comparisons is sent to the web browser via web sockets

   • socket and http server managed by mrqart
   • javascript in static/index.html provides client websockets ingest and styling

Template

See :py:data:`acq2sqlite.DBQuery.CONSTS`

Here's an example for the RewardedAnti task acquisitions in the WPC-8620 project. The ideal template is found finding the most frequent set of repeated key parameters. 150 of the RewardedAnti seqeuences share the same acq_param set, here stored in the sqlite db on rowid=35. But 4 acquisitions (rows in acq) don't match. In this case all mismatches can be found in TA.
