Hi all,
I've been consistently running into the error as shown below:
"
SPM12: spm_est_non_sphericity (v6015) 10:43:10 - 06/06/2016
========================================================================
Chunk 35/35 : ...done
Failed 'Model estimation'

Please check your data: There are no significant voxels.

I've searched for the solution online, including the archives.
I checked smoothed data, volume by volume, no missing data;
I've changed mask threshold to '-inf', didn't work.
I tried a few subjects, thinking it might be something subject specific. not sure, because it worked for some subjects but not all.
It really puzzles me.
just to clarify, here's what I've done:
1. estimate the confounding effects of WM, CSF and motion, save residuals (p.s. it's the resting state data)
2. extract mean timeseries of ROIs
3. specify ROI mean timeseries as the only regressor in an GLM model with residual scans as the input (separate models for each ROI).
Any suggestions/help will be highly appreciated.
Best,
zzang
