Our founding Graph-based technology

Graphia Professional is Kajeka’s founding technology. Originally called BioLayout Express3D, it was developed through a collaboration between the labs of Prof Tom Freeman (University of Edinburgh) and Dr Anton Enright (Sanger Institute/EBI) with funding from the BBSRC. It remains a powerful solution for the creation, visualisation and analysis of graphs derived from large bio-datasets and for pathway modelling and has been referenced in hundreds of academic publications.

Graphia Professional has capabilities for stochastic flow simulations of biological pathways. For all other network analysis needs we recommend our new, modern analysis platform Graphia. Kajeka provide Graphia Pro here as a free Open-source tool for the network analysis community.

To use Graphia professional please sign up for a free account with your institutional email. This will be used to authenticate when using the software.

Active development of Graphia Professional ceased in 2017 as has since been superceded by our modern graph platform Graphia.
