Table 1 Notation of shape parameters and respective morphometric systems analysed by DendroScan. Shape parameters which are mathematically equivalent and therefore would provide redundant information, are omitted by default for DendroScan analyses, but could nevertheless be activated by the user. Definitions for each shape parameter are provided in the second column, with p particle perimeter, A projected particle area, w short side of the minimum area bounding rectangle, b long side of the minimum area bounding rectangle, c perimeter of the circle with area A, a maximum intercept, m mean intercept perpendicular to a, L_b maximum length of all possible lines from one point of the perimeter to another point on the perimeter projected on the major axis of the particle, W_b maximum of all possible lines from one point of the perimeter to another point on the perimeter, projected on the minor particle axis, p_cp perimeter of smallest convex polygon around particle, A_cp area of smallest convex polygon around particle, e_ce perimeter the smallest area ellipse that encloses, but does not intersect the particle, L_maj major axis of best fit ellipse, L_min minor axis of best fit ellipse, d_BC diameter of circle that encloses, but not intersects particle, l_F minimum Feret length, w_F Feret length perpendicular to l_F and d_F maximum Feret distance. For further details see Table 1 in Dürig et al. ³².
