Open Science and Reproducibility are core goals of the MTG, promoting collaborations by making sure that our research results can be used by other researchers and by the society at large. Here we highlight some of the software tools and datasets developed as part of our research and that are being maintained by researchers of the MTG. All our open source projects are made available from our github repository and all our open datasets are made available from Zenodo. Please review the terms and conditions of use stated in each software tool and dataset to make sure that they allow your intended use.

Apart from research collaborations, we are also interested in technology transfer, offering commercial licenses for exploiting our software tools in industrial applications. Contact us for any further information.
