The free, open-source program Samson is available from [http://samson-connect.net samson-connect.net] and in 2020 is under active development by [http://oneangstrom.com OneAngstrom.Com]: see [https://documentation.samson-connect.net/whats-new-in-samson-2020-the-open-molecular-modeling-platform/ What's New in Samson 2020?]. Samson has an extension application named '''''Twister''''' that enables dragging portions of a protein into new conformations with the mouse. Real-time minimization occurs while dragging, following the ''as-rigid-as-possible'' interpolation path<ref name="arap1">PMID:28321532</ref><ref name="low-energy-paths">PMID: 30069648</ref>. | The free, open-source program Samson is available from [http://samson-connect.net samson-connect.net] and in 2020 is under active development by [http://oneangstrom.com OneAngstrom.Com]: see [https://documentation.samson-connect.net/whats-new-in-samson-2020-the-open-molecular-modeling-platform/ What's New in Samson 2020?].
