| Mean analysis time of redundancies and outliers | 13.98 min | 2.5 min | 5.36 min |

A scan space of 261 × 261 images in each dimension was considered. This inflated size of the grid is subsequently corrected in the TR so that the size of the image is not greater than nfibmax = 256 in each dimension, eliminating those cell positions that do not have an appreciable influence on the fibers.
