Marking by Length

This sample describes how to identify sequences with a specified length.

First, the workflow reads sequences inputted by a user. Then, each sequence is marked either as “Short” or “Long,” depending on the sequence’s length. After marking, the sequences are filtered by these marks. Finally, the filtered sequences are written into files as specified by the user.

By default, a sequence with a length of 200 base pairs (bp) or less is marked as “Short.” A sequence longer than 200 bp is marked as “Long.” You can configure this value in the Sequence Marker element parameters.
