10. I cannot find the answer to my question in the FAQ. Whom do I ask for help?
10. What is the order of the regressor columns in the multiple regressors file?
-------------------------------------------------------------------------------
This depends on the physiological models (and their order) specified in the `model`-submodule of physio (or in the batch editor). The general order is outlined in Fig. 7A of the [http://dx.doi.org/10.1016/j.jneumeth.2016.10.019](Main PhysIO Toolbox Paper). The []-brackets indicate the number of regressors:
1. RETROICOR cardiac regressors [2 x nOrderCardiac]
2. RETROICOR respiratory regressors [2 x nOrderRespiratory]
3. RETROICOR cardXResp interaction regressors [4 x nOrderCardiacXRespiratory]
4. HRV [nDelaysHRV]
5. RVT [nDelaysRVT]
6. Noise ROIs (PCA signatures and mean of each region) [nNoiseROIs x (nComponents+1)]
7. Other (included other text file) [nColumnsOtherFile]
8. Motion [6 or 12 or 24, depending on motion model]
If any of the models was not specified, the number of regressors is reduced accordingly.
