Table 2. Input parameters for the bigbrainwarp function.

Parameter	Description	Conditions	Options
in_space	Space of input data	Required	bigbrain, bigbrainsym, icbm, fsaverage, fs_LR
out_space	Space of output data	Required	bigbrain, bigbrainsym, icbm, fsaverage, fs_LR
wd	Path to working directory	Required
desc	Prefix for output files	Required
in_vol	Full path to input data, whole brain volume.	Requires either in_vol, or in_lh and in_rh	Permitted formats: mnc, nii or nii.gz
ih_lh	Full path to input data, left hemisphere surface		Permitted formats: label.gii, annot, shape.gii, curv or txt
ih_rh	Full path to input data, right hemisphere surface
interp	Interpolation method	Required for in_vol. Optional for txt input. Not permitted for other surface inputs.	For in_vol, can be trilinear (default), tricubic, nearest or sinc.For txt, can be linear or nearest
out_type	Specifies whether output in surface or volume space	Optional function for bigbrain, bigbrainsym and icbm output. Defaults to the same type as the input.	surface, volume
out_res	Resolution of output volume	Optional where out_type is volume. Default is 1	Value provided in mm
out_den	Density of output mesh	Optional where out_type is surface. Default is 164	For fs_LR out_space, 164 or 32

Note: the options are subject to change as the toolbox is expanded. Updates will be posted on https://bigbrainwarp.readthedocs.io/en/latest/pages/updates.html.
