Tool Build Statistics for Grids
This tool allows to collect successively cell-wise statistical information from grids by subsequent calls with the 'Reset' flag set to false. The collected information can be used as input for the 'Evaluate Statistics for Grids' tool. Together these tools have been designed to inspect a large number of grids that could not be loaded into memory simultaneously.
