Gmacs User Guide

Welcome to the Gmacs Wiki!

Gmacs is a generalized modelling framework for developing size-structured stock assessment models. Gmacs is an open source program developed using AD Model Builder (ADMB). Gmacs source files will therefore build on any computer that can run ADMB. ADMB is free, open source, and available for Windows, Linux, MacOS, and Sun/SPARC.

There are four major components to the gmacs project:

• The Gmacs assessment model
• The R package gmr
• The code repository (https://github.com/seacode/gmacs)
• Documentation
  • API (http://seacode.github.io/gmacs/)
  • General model description
  • The software manual (this Wiki)
  • Model comparisons

This Wiki is designed as a software manual and developer guide: it describes how Gmacs can be used to develop size-based stock assessment models and provides details about the source code so that interested users can contribute to development.
