[Icatb-discuss] about setupICA

[Quanquan Gu <guq...@gm...>]

Hi experts,

I used the realigned, normlized, smoothed, detrended, filtered and
regressed ( with signals of WM, head motion, CSF regressed ) data sets to
do ICA. I don't know if it's appropriate, some studies used only smoothed
datasets. could you please help me to confirm it? And when I have chosen
the fmri data set (a group of nii files), a error message poped up, showing
:

Creating Mask
Default mask includes voxels >= mean. Using first file of each subject to
create default mask ...

......................................
Group ICA Error Information:


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

is there something wrong with my data format or other settings I got them
wrong?

Thanks in advance
