Dear CONN users,

I successfully preprocessed and denoised my resting-state data in CONN. But when I try to import these preprocessed and denoised data (i.e., niftiDATA*_Condition000.nii) to GIFT to run ICA, I keep getting the following error at the very beginning (when GIFT tries to create a brain mask from the first files of each subject):

Group ICA Error Information:

Error using icatb_createMask (line 176)
No voxels found. Error in creating Mask

I was wondering if this is due to changing the global BOLD signal or averaging BOLD signals during the denoising process (ie,"no significant voxels" issue raised in previous posts about importing results to SPM). 

In GIFT, the first couple of steps are :

1) Creating mask file from functional data
2) Performing data intensity normalization 
3) PCA Type : Expectation Maximization 

Has anyone used the denoised CONN data in GIFT to run ICA successfully?
Any help is highly appreciated!
