Could be important, so here it is: I told you that I replaced the reading in from a file just by the standard set of the parameters (esp for MAGRUN.CFG). Later in the program, where the loops for the ensemble start, these are overwritten, first by the values set in the loops, but also by a set of standard parameters, which are set just before the climate sensitivity loop. First of all, some of these standard parameters are just altered some lines down (TE, XKLO,XKNS), so they are actually never used. Anyway, this is not important. But: Apparently, before these loops, the data read in from the MAGRUN.CFG are already used to do some calculations. The error occured, because at that point I commented these values out where they used to be read from MAGRUN.CFG, because they were set later anyway. Without commenting them out, there is no difference. That means, a part of the program (some initialisation) runs with the parameters from MAGRUN.CFG, the main integration with the parameters set later in the loops. Could this be important for the results? I mean, it causes a quite big difference in the results, so it should be important... Quite scary, the whole program... Anyway, the program runs now, and I can read in data from a new parameter file which R will produce for every iteration. Each one should take less than a second, so we might end up with reasonable times (less than a week on a PC) even for the specificity study for different observational noise. Cheers and have a good weekend!
