This nodes takes a string column and appends the information content of the barcode string into several new columns (e.g. library code, library plate number, project code, assay, date, replicate).
The node uses a regular expression that tries to match the barcode column. Possible barcode patterns can be set at:
KNIME->Preferences->KNIME->HCS-Tools->Barcode patterns
(?<libplatenumber>[0-9]{3})
(?<projectcode>[A-z]{2})
(?<date>[0-9]{6})
(?<replicate>[A-z]{1})
-
(?<libcode>[_A-z\d]{3})
(?<assay>[-_+\s\w\d]*)

Each wanted meta information is marked as a named group and results in a new column.
