Tag / Label #

A tag is a piece of molecule derived data that one step in the pipeline produces, and others may use (or output).

Tags have types: - Location+Sequence (which may loose their location data) - Sequence-only - numeric - boolean

For example ExtractIUPAC produces a ’location’ tag.

That location tag then allows filtering for it’s presence using FilterByTag, cutting the segment at it’s location using TrimAtTag or replacing it’s sequence with LowercaseTag.

Within the steps, tags are consistently referered to as in_label or out_label, depending on whether the step consumes or produces the tag.
