[Eeglablist] STUDY structure in EEGLABv2021

[Delorme, Arnaud]

Dear Fiona,

> I had been doing it as you suggested in the GUI. When I set a group independent variable and selected only one of my groups, the STUDY.design.cases still shows all of the subjects (from both groups). There is nothing in the "included" field. Is this correctly recognizing the subjects of interest?

The cases will show all the subjects, but they will not be plotted.
I have just tried and it worked for me in both the latest version of EEGLAB on Github and the previous released version 2021.0. 

Best wishes,

Arno
