Asking for the sample data in the f-ASL tutorial

[Guobwen]

Hi Andy, I'm studying to analyze ASL data using the f-ASL toolbox these days, following your tutorial of the website https://andysbrainbook.readthedocs.io/en/latest/ASL/04_fASL_GUI.html. However, I cannot find the link of the sample data of the N-back experiment you mentioned, would you be kind enough to provide us with the sample data?
Another question is that if I want to use the f-ASL toolbox to analyze data in my study, which paper should I cite?

  Best wishes!
