On Tuesday 13th April 2021, the H2020 project NanoCommons, in a joint initiative with the NanoSafety Cluster (NSC) and supported by the developments in the H2020 project NanoSolveIT, organized an online webinar on “Online QSAR Modelling Hackathon by Easy Access to Jaqpot”. It was a well-attended webinar, with active and very interested participants who communicated their appreciation at the end of the webinar for the high interactivity and the gained skills. The webinar presentation slides and the recording (recorded for educational purposes) are available in the NanoCommons Infrastructure, in Zenodo, YouTube and in the NanoCommons’ Elixir TeSS channel.
