[Eeglablist] code to add 95% confidence interval shading on all group traces in Study Function

[Kathleen Van Benthem]

Dear List,
I am looking for matlab code (using EEGLAB 2021a) that will allow me to
plot the 95% CIs shading on *each* trace (2 by 2) in the plots created with
the Study function.  As of now, I can only get SDs to shade on one
group/condition combination, but not the other three when
using std_plotcurve().  But I would like all four plotted and the CIs.
thanks,
Kathleen Van Benthem
