Hi, I noticed that both ConfigurationOfPetitParser and ConfigurationOfGToolkit are loading only the Core and Morphic groups from Glamour. However, the code inside depends on visualizations, too, and thus, it needs at least Roassal. So, now I added a Roassal group explicitly in the ConfigurationOfGlamour and had the two other configurations load the Roassal group as well.
