Warning: image_toolbox not valid

Dear REST authors:

I am new to the fMRI and REST toolbox. There was an warning message when I tried to use rest_sliceviewer--'Warning: image_toolbox not valid'. Could you please clarify which image-toolbox referred here? And where can I get it? Thank you very much in advance!

Sincerely yours,

Yong Li, PhD

Hi!
You can choose the option for installing image toolbox when you install the MATLAB.
Best wishes!
