I am try to rebin some data i collected on a Bruker D8 in raw file format. When i use the rebin_width_dx_of command, it performs the rebinning but now all my data is compressed in the 2theta range. My guess is that the program does the rebinning but that the step size is not updated.
does anyone have any ideas what i might be doing wrong?
Thanks,
Mark

Mark,
Your posting surprised me as I've never experienced data compression. That said I'd only ever used rebin_with_dx_of with time of flight neutron data and have used the following two lines together:
rebin_with_dx_of 0.02
x_calculation_step = Yobs_dx_at(Xo); convolution_step 4
The second line works out the calculation step for you. Convolutions are then (very conservatively) on 4 times the step size (slows things down).
I've just tried with a bruker raw file and don't get your problem - even without the second line and going all the way to rebin_with_dx_of 1. Do you want to post your input file?

P.S. when I do use rebinning to speed things up I normally go back to original binning in the final cycle.
