The script is able to <strong>estimate differential stress through paleopiezometers</strong>, implementing multiple piezometric relations for comparison, and to derive the actual (3D) grain size distribution from thin sections using the Saltykov and the two-step methods. The script only requires as input the areas of the grain profiles measured grain-by-grain in a thin section and <strong>does not require previous experience with Python programming language</strong>(see documentation below and <a href="https://github.com/marcoalopez/GrainSizeTools/blob/master/DOCS/FAQ.md">FAQ</a>). For users with coding skills, the script is organized in a modular way facilitating its reuse and code extension.<br></p>
