Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_artifact_jump”.

  FT_ARTIFACT_JUMP reads the data segments of interest from file and identifies
  SQUID jump artifacts.
  Use as
    [cfg, artifact] = ft_artifact_jump(cfg)
  with the configuration options
    cfg.dataset     = string with the filename
    cfg.headerfile  = string with the filename
    cfg.datafile    = string with the filename
  and optionally
  Alternatively you can use it as
    [cfg, artifact] = ft_artifact_jump(cfg, data)
  where the input data is a structure as obtained from FT_PREPROCESSING.
  In both cases the configuration should also contain
    cfg.trl        = structure that defines the data segments of interest. See FT_DEFINETRIAL
    cfg.continuous = 'yes' or 'no' whether the file contains continuous data
  The data is preprocessed (again) with the following configuration parameters,
  which are optimal for identifying jump artifacts.
    cfg.artfctdef.jump.medianfilter  = 'yes'
    cfg.artfctdef.jump.medianfiltord = 9
    cfg.artfctdef.jump.absdiff       = 'yes'
  Artifacts are identified by means of thresholding the z-transformed value
  of the preprocessed data.       = Nx1 cell-array with selection of channels, see FT_CHANNELSELECTION for details
    cfg.artfctdef.jump.cutoff        = z-value at which to threshold (default = 20)
    cfg.artfctdef.jump.trlpadding    = automatically determined based on the filter padding (cfg.padding)
    cfg.artfctdef.jump.artpadding    = automatically determined based on the filter padding (cfg.padding)
  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.
