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
Error in ==> icatb_createMask at

Error in ==> icatb_update_mask at

Error in ==> applyCallback at

......................................
Error using icatb_displayErrorMsg (line 23)
Error in icatb_setup_analysis>applyCallback (line 1519)
icatb_displayErrorMsg;
Error while evaluating uicontrol Callback
is there something wrong with my data format or other settings I got them
wrong?
Thanks in advance
regards,
Carmen
