FT_ARTIFACT_NAN
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_artifact_nan”.
FT_ARTIFACT_NAN identifies artifacts that are indicated in the data as nan (not a number) values. Use as [cfg, artifact] = ft_artifact_nan(cfg, data) where the input data is a structure as obtained from FT_REJECTARTIFACT with the option cfg.artfctdef.reject='nan'. The configuration can contain cfg.artfctdef.nan.channel = Nx1 cell-array with selection of channels, see FT_CHANNELSELECTION for details The output argument "artifact" is a Nx2 matrix comparable to the "trl" matrix of FT_DEFINETRIAL. The first column of which specifying the beginsamples of an artifact period, the second column contains the endsamples of the artifactperiods. To facilitate data-handling and distributed computing you can use cfg.inputfile = ... If you specify this option the input data will be read from a *.mat file on disk. This mat files should contain only a single variable named 'data', corresponding to the input structure.
