Hi Liam: I agree with Matt. I don't find phase corrected plots to be very useful. Rather, I try to just identify peak positions without trying to interpret what the half-path length might be. I leave that for the results of the fitting. As a secondary, but perhaps more important point,

Hi Liam, Yes, this is not currently available. It would not be hard to enable, but I am not sure it is a great thing to do. I admit that I sort of find that phase-correction plots need a lot of explanation, and so are prone to causing confusion. They might be useful for Pt metal, but they

Dear all, In Artemis it is possible to plot chi(R) for FEFF-fit, with the phase corrected - i.e. bond length corrected for deltaR. This is shown in this screenshot below ("Use this path for phase corrected plotting"). Is this possible in XAS Viewer? [cid:b58a0f44-1946-4c60-a12e-c1e0bfa50100]

Dear Matthew, I thank you very much for your quick reply as well as this of Carlo Segre. I apologize, I did not look at the archived messages and now it is clear. I will try to install Larch as you said and keep you in touch if I have any trouble or success ! Bests, Laurent De: "Matt
