The following line of code removes articfacts resulting from field inhomogeneities with a bias field correction using Advanced Normalization Tools (ANTS) (Website download: https://github.com/stnava/ANTs.git) The input is the acpc-aligned T1 NifTi file and the output is a compressed T1 NifTi file corrected for field inhomogeneities. The -d indicates the image dimensionality; -s indicates the shrink factor; -b indicates spline distance; and -c gives the convergence in number of iterations and threshold.
