[FieldTrip] Running cluster-based permutation test on fMRI data

[Maris, E.G.G. (Eric)]

Hi Lene,

The cluster-based permutation test ran without any problems using ft_sourcestatistics on volumetric fMRI data... Of course, I am now hooked on trying out the randomization framework outlined on the OHBM poster and in the bioRxiv manuscript. May I ask when the corresponding Fieldtrip functions become publicly available? I do not want to pin you down on an exact date in any way but am rather wondering if it makes sense to wait for those functions and defer my current analysis for a few days/weeks.


You should not wait. I haven’t even discussed Fieldtrip (FT) integration with the development team, although such integration would definitely be feasible. I expect that first-level analyses and normalization have to be performed outside of FT, and the resulting nifti files imported into FT. This will require quite some bookkeeping.

Best,
Eric
