 To avoid to download everything at once, this is a 2 steps process:
 - 1/ We set a list of users for which we want to get the list of sequences to download, and get a bash script for each user.
    Change the list of users in the batch file `batch_get_username.sh`. 
-   change the access token with your access token and the sequence ids with the ids of the sequences you want to download
    ```bash
    usernames=( "someone_having_nice_pictures" "someone_else" "oh_look_a_these_usernames" ) # use real accounts, it might work better

    This will give you a few files that the other scripts will use to generate a script to download all sequences of each user. One user, one bash script generated.
