Brian and Jo, It happens to me that the flag unticks itself only when you open the dropdown menu to select the correction and then tick the flag. If after the first cycle with the flag unticked you tick again without opening the menu the correction is applied nicely and the flag remains ticked. HTH. Leo

Do you have evidence (all very low angle peaks computing much higher than observed) for a need for the correction? The flag should not "untick" itself in EXPGUI unless the @#$#^& author got it wrong again.

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.
