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

This is an example:

Selected Barcode Pattern: (line breaks only for better visualization)
(?<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]*)

	Extracted metadata columns
Barcodes from input column	library plate number	project code	date	replicate	library code	assay
001AL100914C-CPW1nMovn	1	AL	100914	C	CPW	1nMovn
006AL100914A-CPW1nMovn	6	AL	100914	A	CPW	1nMovn
001MB140502D-KBI_lowGlucose	1	MB	140502	D	KBI	_lowGlucose

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

Definition pattern: (?<groupname> regular expression )

The group name will be the name of the new column, beside a few exceptions:

group name	column name
libplatenumber	library plate number
libcode	library code
projectcode	project code
concunit	unit of concentration
