Hello, Would it be possible to get a "save un-checked particle" option in Plotwin ? I managed to do it by hiding checked particles and then saving all particles but a direct way would be appreciated. I also tried to use the "lost particles" but I don't quite understand how it works ! Thanks in advance

When trying to backtrack a proton beam through a LEBT, a virtual collimation is generated at the end of a fieldmap. It seems to be due to the fact that the later fielmap is superposed to another (problem disappears when overlapping removed).
