Injection Metadata props

Peaksel parses and stores the metadata of the injections in injection properties. These show up on UI, can be used in the batch-level visualizations and can be searched using direct SQL against the database:

inj props
Currently it’s supported only for Waters MassLynx. If you need the support for other formats, get in touch and we’ll implement it.

By default these properties are being stored if they are stored:

  • In Waters MassLynx the properties are stored in _HEADER.txt

    • Conditions

    • Laboratory name

    • Sample description

    • Solvent delay

    • SpareN (1 through 5)

Configuring properties

At the moment available only for on-prem instance.

By default only a few properties are being stored. You can configure which properties are being stored and how they are named by modifying import_props_preprocessors in Global Properties:

[
  {"propName": {"renameTo": "some new name"}}
]

If you want a property that’s not in the default list, you can add it here.

Optionally, rename it to something else - this can be helpful in unifying them if different vendors use different prop names.

User-defined properties

You can override the value that was stored in the raw metadata with user-defined properties.

Peaksel won’t delete the old value, so it’s possible to revert the change later.
