Surface to volume — surf_to_vol • VertexWiseR

Converts surface data to volumetric data (.nii file)

Usage

surf_to_vol(surf_data, filename, VWR_check = TRUE)

Arguments

surf_data: A numeric vector or object containing the surface data, either in fsaverage5 (1 x 20484 vertices) or fsaverage6 (1 x 81924 vertices) space. It can only be one row of vertices (not a cohort surface data matrix).
filename: A string object containing the desired name of the output .nii file (default is 'output.nii' in the R temporary directory (tempdir())).
VWR_check: A boolean object specifying whether to check and validate system requirements. Default is TRUE.

Value

A .nii volume file

Examples

CTv = runif(20484,min=0, max=100);
surf_to_vol(CTv, filename = paste0(tempdir(),'/volume.nii'), VWR_check=FALSE)
