At this point, Larch *should* be able to do this too. That is to say, the feffit() function in Larch can propagate uncertainties in chi(k) through the EXAFS analysis steps. It definitely needs more testing and I'm not at all certain this is done the same way you're doing it. Currently, Larch does not currently propagate uncertainties in measured intensities to uncertainties in mu(E) in any automated way, and also doesn't propagate uncertainties in mu(E) to uncertainties in chi(k). The basic tools to do these are available, and I think it would not be hard to add these features. A simple test case of full error propagation would be really helpful. --Matt
