Errts overlay not seen

AFNI Message Board

Dear AFNI experts,

I just ran proc.py (example 11 with FreeSurfer) for the resting state fMRI data. I was then checking the data quality and found that nothing was shown when errts.fanaticor file was overlayed to anat.final file for this participant (the first image attached). I did align the epi and anat files using the align_epi_ant command (the second image attached), so I am not sure what is the issue here. I have never seen this before. Other subjects’ data were fine. Could you please advise what could be an issue here?

Best,
JW

Hi JW,

Try changing the overlay volume index. It seems likely that volume #0 was censored in the regression and so is all zero.
