The desired order of transformation (1, 2, or 3) is selected with the order option. -v.rectify will calculate the RMSE if the -r flag is -given and print out statistcs in tabular format. The last row gives a -summary with the first column holding the number of active points, -followed by average deviations for each dimension and both forward and -backward transformation and finally forward and backward overall RMSE. +If the -r flag is given, v.rectify will calculate the +Root Mean Square Error (RMSE) and print out statistics in tabular format. +The last row gives a summary with the first column holding the number of +active points, followed by average deviations for each dimension and both +forward and backward transformation and finally forward and backward +overall RMSE.
