+nichart Mode
+============
+
+The ``nichart`` mode is used by the `NiChart project <https://neuroimagingchart.com/>`_.
+
+This mode is very similar to ``linc`` mode, with the exception that it processes NIfTI files
+by default and has smoothing disabled.
+
+Defaults
+--------
+
+By default, the ``nichart`` mode will apply the following parameters,
+which may be overridden by the user:
+
+-  ``--file-format nifti``: NIfTI files are used as input.
+-  ``--despike``: Despiking is enabled by default.
+-  ``--fd-thresh 0``: Motion-based censoring is disabled by default.
+-  ``--input-type fmriprep``: fMRIPrep outputs are expected as input.
+-  ``--linc-qc``: The LINC QC file will be created by default.
+-  ``--min-coverage 0.4``: The default coverage threshold is 0.4 instead of the more common 0.5.
+-  ``--output-type censored``: Censored data are the primary output.
+-  ``--smoothing 0``: Smoothing is disabled by default.
