+ | Note that this reference documentation is identical to the help that is displayed in MATLAB when you type "help ft_removetemplateartifact". | ||

+ | <html><pre> | ||
+ | <a href=/reference/ft_removetemplateartifact><font color=green>FT_REMOVETEMPLATEARTIFACT</font></a> removes an artifact from preprocessed data by template | ||
+ | subtraction. The template can for example be formed by averaging an ECG-triggered | ||
+ | MEG timecourse. | ||
+ | |||
+ | Use as | ||
+ | dataclean = ft_removetemplateartifact(cfg, data, template) | ||
+ | where data is raw data as obtained from <a href=/reference/ft_preprocessing><font color=green>FT_PREPROCESSING</font></a> and template is a averaged | ||
+ | timelock structure as obtained from <a href=/reference/ft_timelockanalysis><font color=green>FT_TIMELOCKANALYSIS</font></a>. The configuration should | ||
+ | be according to | ||
+ | |||
+ | cfg.channel = Nx1 cell-array with selection of channels (default = 'all'), see <a href=/reference/ft_channelselection><font color=green>FT_CHANNELSELECTION</font></a> for details | ||
+ | cfg.artifact = Mx2 matrix with sample numbers of the artifact segments, e.g. obtained from <a href=/reference/ft_artifact_eog><font color=green>FT_ARTIFACT_EOG</font></a> | ||
+ | |||
+ | 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. | ||
+ | |||
