just to comment about this, i had the time to test out this approach, and it is not good enought, and the path given is a little bit problematic, as i wanted to have a file on the root of the folder, and with the division of the files on the processors or not in the processors (i mean if run in parallel or in serial) the relative path will be different... and the absolute one will be case dependant so I will do something similar, but instead that will read the values and sed it from the file during the allRun, this looks more robust, simply that is not general and need to change the sed command in different simulations..
