CFWP and WNvW taught a pre-conference course at the IBS Channel meeting 2017 hosted by Hasselt University. The course, entitled "Network modelling for high-dimensional data", focussed on the reconstruction -- de novo or with prior information -- of networks from such data, but also on the analysis and exploitation of the reconstructed networks. The course provided loads of hands-on experience due to practicals illustrating our homegrown R packages 'rags2ridges' and 'ragt2ridges' that implement the presented analyses. With over 40 participants and overwhelmingly enthousiastic reactions, to be rerun.
