FT_REJECTCOMPONENT
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_rejectcomponent”.
FT_REJECTCOMPONENT backprojects an ICA (or similar) decomposition to the channel level after removing the independent components that contain the artifacts. This function does not automatically detect the artifact components, you will have to do that yourself. Use as [data] = ft_rejectcomponent(cfg, comp) or as [data] = ft_rejectcomponent(cfg, comp, data) where the input comp is the result of FT_COMPONENTANALYSIS. The output data will have the same format as the output of FT_PREPROCESSING. An optional input argument data can be provided. In that case componentanalysis will do a subspace projection of the input data onto the space which is spanned by the topographies in the unmixing matrix in comp, after removal of the artifact components. Please use this option of including data as input, if you wish to use the output data.grad in further computation, for example for leadfield computation. The configuration structure can contain cfg.component = list of components to remove, e.g. [1 4 7] or see FT_CHANNELSELECTION cfg.demean = 'no' or 'yes', whether to demean the input data (default = 'yes') cfg.updatesens = 'no' or 'yes' (default = 'yes') To facilitate data-handling and distributed computing you can use cfg.inputfile = ... cfg.outputfile = ... If you specify one of these (or both) the input data will be read from a *.mat file on disk and/or the output data will be written to a *.mat file. These mat files should contain only a single variable, corresponding with the input/output structure. See also FT_COMPONENTANALYSIS, FT_PREPROCESSING
