Group :  All

(iii) You can choose to limit the length of the signal sequences that you're searching. Please note that based on the data we have, we have omitted sequences which are less than 11 residues if you've selected the filtered data. Otherwise, you can search by any length.

Sequence Length :  All
 less than  
(if data filtering is selected, signal sequences less than 11 residues are omitted by default.)

(iv) You can select the number of entries you want to view per page on the result page. The minimum is 10 entries per page and maximum is 50 entries per page.
