Dear Jaspar team,

I am currently a biotechnology student and thus not very proficient in using Jaspar. For a module, I am tasked with finding the most probable promoter sequence region for FGF21. For this, I would like to scan my sequence of interes for all profiles for homo sapiens. Now comes my question:

For now, I did the tedious task of putting 250 profiles per page for 9 pages in total, into the basket, before I ran a scan. 
Is there a quicker way to do this? Do you provide or have any tutorials available, that could help me? Because if I use this method, I would have to manually exit all entries in the basket before tediously adding all profiles again, if I wanted to switch to another species for example. I am sure, you have a quicker and easier way to do this.
Thank you very much!

Kind regards
Cihan

Hi Cihan.

We recommend to use the pyJASPAR python module (https://pyjaspar.readthedocs.io/en/latest/) to retrieve the PFMs that you are interested in and then use them to scan any FASTA sequence you want.
