Subject: applying instrumental corrections directly to data
I want to test the implications of instrumental effects on some analysis I am doing outside of TOPAS. Is there a way to use TOPAS to correct the measured data directly (e.g. LP correction, axial divergence etc.), rather than applying the effects to a simulated pattern as done with Rietveld refinement?

Subject: Anisotropic adps with PDF refinement
Hello,
I would like to refine anisotropic adps with PDF data (for example refining u11,u22,u33 separately to test the effects of highly direction-dependent correlated motion). However, they do not work with the pdf data-type. After reviewing "Coelho, Chater &, Kern, J. Appl. Cryst. (2015). 48, 869–875", I see that the algorithm is only considering isotropic adps. I am wondering if there is currently any way around this, or if this is something that might be implemented in future versions?

Thanks!
Max
