Dear Expert,

I got fMRI data obtained with a ASL perfusion MRI method. With using Perfusion Toolbox on the SPM5, I obtained CBF and PWI time course images.
After pre-processing and during analysing ASL perfusion fMRI data using SPM5, we got the following message during the "Model Estimation"

"No inmask voxels-empty analysis"
 
Does anyone know how to solve this error message?

I appreciate any comments.

 

Best

Geon-Ho
