Dear Conn-experts,

I´m planning to use the denoised nifti output from CONN as input to the GIFT toolbox. I used the function conn_matc2nii.m to convert the matc files in the results/preprocessing folder to get the denoised nifti files. 

Are these indeed the correct denoised nifti images that I can feed into GIFT to run a group ICA analysis?

My concern is that in the denoising step I used linear detrending and in the GIFT toolbox there is one preprocessing step to remove the mean per timepoint that cannot be deselected. How having linear detrending prior to this removal of the mean per timepoint will affect the results? Should I repeat the denoising without linear detrending?

Thank you in advance for your help.

Best wishes,
Noelia
