That is fine. I don't think that there are any conventions you need to follow (it should just be an Nx6 matrix

I have used bbr to register all EPI volumes in my time series to the brains of my participants. The fMRI time series at each vertex was determined based on this registration. I would like to use motion regressors in the GLM analysis. Is it appropriate to extract the motion parameters from the bbr registration matrices to use them as input to mcdat2mcextreg? Are there any conventions I need to take into account?
Best Joerg
