The free distribution often strips out the manual. You are left with a single readme.txt that assumes you already know the difference between "Gaussian response" and "Hofker's method." New users will be lost.

GRADISTAT was developed by Simon J. Blott and Kenneth Pye, with its methodology and original software published in 2001 in the journal Earth Surface Processes and Landforms . The program was designed for the rapid analysis of grain size statistics from data obtained through standard measuring techniques like sieving and laser granulometry. Its integration into Microsoft Excel made it extremely versatile, accepting both standard and non-standard size data and producing key graphical outputs.

: As an Excel template, it allows users to input weight or percentage data from sieving or laser granulometry directly into a spreadsheet format. Useful Resources for Version 9.1 gradistat v 91 free
