DAMNIT

The tool in a nutshell

The DAMNIT GUI provides a tabular, aggregated view on data and metadata
as soon as new content from experiment data acquisition is available.

Benefits of using DAMNIT

DAMNIT has been designed with the following purposes in mind:

• Replace spreadsheets for the purpose of logging sequences of measurements
• Standardise the metadata content to be tracked and evaluated
• Automate the creation of entries as soon data are collected
• Be close to online monitoring for reasonably fast decisions
• Have rich data visualisation with various graphs for free
• Embed complex data analysis to the workflows where needed

European XFEL data are collected in runs. The automatically built
DAMNIT tables help to compare data runs which is crucial to detect:

• trends of data quality
• opportunities for data selection
• opportunities for data aggregation
• correlations with the experimental setup
  (e.g. beam, sample, detector configuration)

The DAMNIT feedback is as fast as file-based workflows allow:

• Live monitoring is complemented on a minutes timescale
• This "close-to-online" principle allows for efficient high-level decisions
