RE: Using CONN preprocessed and denoised data to do ICA in GIFT
Hi Merle,
I believe this may be related to an issue which was already addressed in release 19b. When using any of the more recent versions of CONN (19b or above) the new denoised functional data will maintain the average/anatomical information of the original functional data, so that it is more compatible with several software packages which rely on the average BOLD signal to estimate a reasonable brainmask from the functional data.
(note: in these newer versions, the denoised functional data will be stored in the same directory as your original functional data and prepended with the letter 'd', instead of using the previous niftiDATA*.nii convention for these files)
Hope this helps
Alfonso

Hello,
did you find a solution for the below-mentioned problem?
We've been trying to run spatial ICA in GIFT using denoised fMRI data (niftiDATA*_Condition000.nii) from CONN, but we keep receiving this error message:
Group ICA Error Information:
Error using icatb_createMask (line 176)
No voxels found. Error in creating Mask
Is there an easy fix to this problem?
Best,
Merle
