Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_preproc_denoise”.
FT_PREPROC_DENOISE performs a regression of the matrix dat onto refdat, and subtracts the projected data. This is for the purpose of removing signals generated by coils during continuous head motion tracking, for example. Use as [dat] = ft_preproc_denoise(dat, refdat, hilbertflag) where dat data matrix (Nchan1 X Ntime) refdat data matrix (Nchan2 X Ntime) hilbertflag specifying to regress out the real and imaginary parts of the hilbert transformed signal. Only meaningful for narrow band reference data See also PREPROC
