GrainSizeTools script manual

This is the manual for the GrainSizeTools script. GrainSizeTools script is a free open-source cross-platform script written in Python that provides a number of tools with the aim of characterizing the grain size and the actual population of grain sizes in dynamically recrystallized rocks. The script is suitable to use in paleopiezometry studies, returning different 1D grain size measures, as well as to derive the actual 3D population of grain sizes from thin sections using two methods: the Saltykov and the two-step methods. The script only requires the previous measurement of the grain sectional areas from a thin section. There is no need of previous knowledge of Python language to use the script and get the results. For advanced users, the script is organized in a modular way using Python functions, which facilitates to modify, reuse or extend the code if needed.本手册为GrainSizeTools脚本使用手册。GrainSizeTools脚本是一款基于Python开发的免费开源跨平台工具集，旨在实现动态重结晶岩石的晶粒尺寸及其实际粒径分布的表征。该脚本适用于古压力计量研究，可输出多种一维晶粒尺寸度量结果，同时支持通过两种方法（Saltykov法与两步法）从薄片数据中推导得到实际的三维晶粒尺寸分布。本脚本仅需预先通过薄片测得晶粒截面面积即可运行，用户无需具备Python语言相关前置知识即可使用本脚本并获取计算结果。对于高级用户而言，本脚本采用Python函数以模块化架构进行组织，便于按需对代码进行修改、复用或扩展。
