New advanced tutorial

We now have a significant number of researchers and product development scientists using PoreXpert version 2.  However, Covid-19 restrictions have prevented us from organising training courses.  Therefore we have posted a new advanced tutorial at https://www.porexpert.com/help2/index.html?artefacts-and-stochastic-realisations.htm.  It is required reading, as it explains how to avoid false results generated by the program itself – artefacts.  We wish all our users the best possible Christmas and New Year in these very difficult times.
