Using CONN preprocessed and denoised data to do ICA in GIFT

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):

[color=#ff0000][b]Group ICA Error Information:[/b][/color]
[color=#ff0000][b][/b][/color]
[color=#ff0000][b]Error using icatb_createMask (line 176)[/b][/color]
[color=#ff0000][b]No voxels found. Error in creating Mask[/b][/color]

I was wondering if this is due to changing the global BOLD signal or averaging BOLD signals during the denoising process (after reading posts this post: https://www.nitrc.org/forum/message.php?msg_id=19383  and "[u]no significant voxels[/u]" problem). 

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<span id="_plain_text_marker"> </span>

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