Hello all, Using expgui (GSAS) and I am trying to get some bragg-bretano flat plate surface roughness corrections on the go.
I have used the absorption for cylindrical samples (tof) when I define the number but whenever I try to refine the quantity and run genles it resets to zero and unticks itself everytime. Is it the case that you have to enter the absorption coeffs yourself? If so, why is there a tick box? Thanks in advance. Jo
