`files` |
Vector of full paths to images or a list of local nifti objects |

`brainMask` |
Full path to brain mask or local nifti object |

`subMask` |
NULL or local nifti object or the full path to a mask that is a subset of brain mask where coupling should be computed |

`type` |
"regression" or "pca" |

`ref` |
reference modality when type="pca" or dependent modality when type="regression" |

`fwhm` |
Full width in voxels for FWHM |

`thresh` |
Threshold for trimming Gaussian kernel weights |

`radius` |
radius of neighborhood in number of voxels. Can be specified instead of fwhm. Default is NULL and overrides fwhm when specified as non-NULL. |

`reverse` |
If TRUE, calculates both regressions if type="regression" and length(files)==2, otherwise ignored |

`verbose` |
TRUE for updates on computation, else FALSE |

`retimg` |
If TRUE, return list of estimated coupling maps as nifti objects |

`outDir` |
Full path to directory where maps should be written |

`propMiss` |
Maximum proportion of missing voxels in a neighborhood to tolerate, i.e., return NA if missing more than propMiss in the neighborhood of the center voxel |

Estimated IMCo coupling maps, either written to files and/or returned as nifti objects
