Marking by Annotation Number

This sample describes how to identify sequences with a specified number of annotations.

First, the schema reads sequences input by a user. Then, each sequence is marked with either the “Good” mark or the “Rest” mark, depending on the number of annotations in the sequence. After marking, the sequences are filtered by the marks. Finally, the filtered sequences are written into files specified by the user.

By default, a sequence with 1 or more annotations is marked as “Good.” You can configure this value in the Sequence Marker element parameters. It is also possible to set up the annotation names that should be taken into account.
