Variability of shape features is influenced by scanner, vendor, acquisition, and b-value. Variability is shown as MAPE for each TractSeg, ATK, and Reco methods, for scan-rescan (RESCAN), scanners (SCAN1, SCAN2), vendor (VEN1, VEN2), resolution (RES1, RES2), diffusion directions (DIR1, DIR2) and b-value (BVAL). Values shown are averaged across all pathways within a bundle dissection method. Shape features are ordered (from top to bottom) from lowest to highest average MAPE. Many shape features are highly reproducible, and MAPE is influenced by all effects investigated.
