TIP. To return sequences longer than a certain length, set Minimal length to desired value and leave Maximum length set to '0'.
What it does
Outputs sequences greater than or equal to Minimal length and less than or equal to Maximum length.
Example
Suppose you have the following FASTA formatted sequences:
>seq1 TCATTTAATGAC >seq2 ATGGC >seq3 TCACATGATGCCG >seq4 ATGGAAGC
Setting the Minimal length to 10, and the Maximum length to 0 will return all sequences longer than 10 bp:
>seq1 TCATTTAATGAC >seq3 TCACATGATGCCG
