error using rest toolkit

Hi, dear all
The output Images of  ReHo or ALFF were distored, when I open them with MRICRo.
Please help me, what was happen? attached I send the output image of toolkit.

This image can be opened by MRIcroN other than MRIcro.
By the way, this image does not look like ReHo or ALFF image.
