Hi I'm right now working on a process flow generator which generates LaTeX and from there a PDF out of a YAML file in which the process is nicely written down. The key is here that you can add requirements for preparation steps between machines and it automatically checks for contamination control violations. What do you think? Might that be useful for anyone else except us? For us it will be very useful, because we won't make mistakes when planning processes anymore, at least on the contamination level. Cheers David
