Hi!
Please resample your mask or ROI file to the dimension of your
functional images in REST.
You can use SPM to reslice your image as follows:
a.
Click "Coregister"
b.
Click "New "Coreg: Reslice""
c.
"Image Defining Space": choose one of your functional image. e.g. your
normalized functional image or image after Detrend and Filter.
d.
"Images to Reslice": choose the mask file or ROI definition file. e.g.
BrainMask_05_61x73x61.img
e.
"Reslice Options" -> "Interpolation": choose "Nearest neighbour"
f.
Just click "Run". Then you will get the resmapled mask or ROI file with a
surfix of "r".
And the new release of REST is coming soon (maybe in one
or two weeks), we have added this function to REST, and you can reslice the
images in a batch mode.
Best wishes!
Yours
Sincerely,
YAN
