[FieldTrip] Runica: Output argument "sphere" (and maybe others) not assigned during call to "runica"

[Margerison, Sarah]

Hello,

I am getting the following error message attempting to use runica:  Output argument "sphere" (and maybe others) not assigned during call to "runica"

This is occurring in a script which was working a few weeks ago when I ran it last.  We are running fieldtrip version 20211008 on Matlab 2019b.  As far as I know, nothing has been updated since I last used the script.

Currently, these are the fields in the cfg variable:
length = 4
overlap = 0
method = 'runica'
runica = 1x1 struct (cfg.runica.pca =15)

I've also used length = 1.75 and pad = 4 and had the same issue.

I ran which runica and got the following: /usr/local/EEGLAB2022/eeglab2022.1/functions/sigprocfunc/runica.m

I understand that this is an externally called function, but I am still hoping to get some clarity on what might be wrong.  Is there a specific field I should be adding that I am not? And what is the possible reason for the script to no longer want to run?

Thanks very much for your help!
