[FieldTrip] 2x3 ANOVA depsamplesHotTsqr

[Julian Keil]

Dear Lin, Aykut and Alex,

I wrote a fieldtrip-compatibe wrapper function to the ANOVA-Functions by Trujillo-Ortiz (the originals can be found on the Matlab File Exchange) which can handle n-way repeated ANOVAs.
These functions can handle timlock, TFR or source-level FT structures.
The code can be found on by Github: https://github.com/juliankeil/VirtualTools
Please be aware, that these ANOVA-functions in DO NOT use a permutation approach or provide any correction based on clusters. All correction for multiple comparisons has to be done after running the ANOVA.

Some recent examples in which these functions were used are:
Keil, J., Pomper, U., Senkowski, D., 2016. Distinct patterns of local oscillatory activity and functional connectivity underlie intersensory attention and temporal prediction. … Cortex 74, 277–288. doi:10.1016/j.cortex.2015.10.023
Roa Romero, Y., Keil, J., Balz, J., Gallinat, J., Senkowski, D., 2016a. Reduced frontal theta oscillations indicate altered crossmodal prediction error processing in schizophrenia. J Neurophysiol 116, 1396–1407. doi:10.1152/jn.00096.2016
Roa Romero, Y., Keil, J., Balz, J., Niedeggen, M., Gallinat, J., Senkowski, D., 2016b. Alpha-Band Oscillations Reflect Altered Multisensory Processing of the McGurk Illusion in Schizophrenia. Frontiers in Human Neuroscience 10, 41. doi:10.3389/fnhum.2016.00041

Maybe these reference suggested by an anonymous reviewer could be helpful in the implementation of a permutation approach:
Anderson, M., Braak, C., 2002. Permutation tests for multi-factorial analysis of variance. Journal of Statistical Computation and Simulation 73, 85–113.
Anderson, M.J., 2001. Permutation tests for univariate or multivariate analysis of variance and regression. Can. J. Fish. Aquat. Sci. 58, 626–639. doi:10.1139/cjfas-58-3-626

Good luck,

Julian
