Hi Edward, I would like to look at the calculation progress, by extracting the chi2 values from the results in tensor/round_*/opt folder. A while ago a script for this was posted (https://mail.gna.org/public/relax-users/2007-06/msg00017.html), but the relax syntax changed since then. I have figured out the beginning, but not sure where the MF parameters are called (chisq=self.relax.data.chi2[name] in the older script). Thank you, Vitaly
