Using the extract functions
Both functions create new specimens that have have an OTU det that is that of the present lot, and also the same collecting event, if there is one attached.
This function creates a new specimen from the lot. It subtracts 1 from the “value” specimens in the lot. It is not available if there are no “value” specimens.
create (clone, no extraction)
