Using that scheme you can select (or reject) only those sequence that match any pattern you input.
To find sequences matching a pattern:
1. In Read Sequence element specify a list of sequences you need to filter
2. In Find Pattern element input you pattern(s) or file with pattern in any sequence or newline-delimited format.
3. In Write Sequence element specify an output file
To find sequences that DO NOT match a pattern:
Put "Rest" instead "hasPattern" in Filter element.
