Gentlemen,
I've been listening for a week or so and I am really wondering what do you
want to get ... Actually you are setting up a "refinement", whose results
will be, at least, inaccurate. I am always surprised by attempts to refine
crystal structure of a disordered sheet silicate from powders, e
Dear Leandro Bravo,

In the refinement of chlorite minerals with well defined disordering

intensive peak) and k 3.n
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.

Jo,
The surface roughness coefficients can be refined, but they can
be very touchy. 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 @#$#^&

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
Sorry about that.

Simon,
You left a couple of jackets at my house - they're on their way back to
you.
Did you see anything interesting with the realtor? Do let us know if
you'll be coming back for another visit with your wife.
Best,
Peter
