Two versions of the tool have been developed. The first one, managing computationally intensive processes for step 1, is written in C-ANSI and runs in command line, which provides a convenient integration with custom analysis pipelines and databases. The second version integrates the C program and additional functionalities within a graphical user interface (GUI) coded in C++ using Qt, Qwt & Graphviz libraries. Installable versions are distributed to run under most modern GNU/Linux, Windows (XP/7/8) and Mac OS X (10.5 or later with Intel processor) systems.

Although completely standalone, with data imported via simple plain-text formats (documented on our web site), OptiMAS is part of the Integrated Breeding Platform (IBP), a web-based workflow system providing analytical tools and services to help breeders to improve crops for greater food security in the developing world (https://www.integratedbreeding.net).

- Maize (biparental): The data set example is coming from a biparental population (F2-F252) of 300 F3 individuals that were evaluated during 2 years in several trials. The results of the QTL detection were published in Huang et al., Genetics, 2010. We selected 10 QTL based on an index evaluated for dry grain yield and grain moisture. A set of 39 markers were selected with ~4 flanking markers/QTL.
- Maize (multiparental): 6 F2 populations, with 150 individuals each, were obtained from a diallel cross between 4 connected unrelated maize inbreds (DE, F283, F810 and F9005). 10 QTL were detected for silking date (Blanc et al., Theor Appl Genet, 2006). A set of 34 markers were selected with ~3 fully informative (microsatellites) flanking markers/QTL. 2 cycles of MARS were performed with each time step of selfing process.
