Issue running mediation_brain #25
Description
Hello everyone,
This is the first time I'm trying to run a mediation analysis using this toolbox and I've run into some trouble.
Entering this line of code in matlab (Version 2021b)
results = mediation_brain(X,Y,M,'names',names,'mask', mask, 'noverbose');
I get the following error (copied below) which at first glance seems to be related to the tcdf code from matlab... but is it really required to have the Deep Learning Coder and the Deep Learning Toolbox installed for running the mediation? Because this is what I found online as suggestion to resolve part of the error message "Unable to resolve the name coder.internal.sxalloc".
Unfortunately I don't currently have the Deep Learning Toolbox for matlab ..... Any help is much appreciated, as running this analysis would help me finish a project :-)
Thank you and best wishes,
Vanessa
