Hello everyone, In our lab, we like the segmentation from CAT12, the extension of SPM12. After visual checks, we found that this segmentation pipeline gives us good estimates of GM...

Hi @gracehsu, > I wonder if there's any suggestion for the number of PCA components for aCompCor using WM & CSF masks? (currently I'm using "5") Personally, I would not...

@SaraCal No worries. @mrikasper 1. **Warning at reslice** Yes this warning can be transformed into a normal logging message, since it should not raise a particular attention. 2. `nVoxels n...

Hello, SPM team's strategy works to fetch one PC whatever the ratio nVoxel / nVolume, using the covariance matrix. I tested it on synthetic data. Here is almost the same...

Hello, Same for me, I will probably be attending OHBM, but not ISMRM. But is there are discussions about PhysIO developments, I'm in ! Best, Benoît

Hello @gracehsu, > Does PhysIO toolbox allows non-MNI space? TAPAS/PhysIO does not depend on the space it-self (native vs normalized). The noiseROI part checks the `geometry = orientation(header) + gridsize(resolution)`....
