Dear Navin, Maybe a little more explanation: the merging of different runs is done by the scaling program. There is nothing special with different 2theta angles, the only thing is that the scaling program should know about it for applying absorption corrections etc. This is handled automatically and should not require user intervention. For XSCALE you can read in multiple HKL files, for scala/aimless, as Tim pointed out, you first have to combine the different mtz files into one. Scale/aimless should also automatically detect the different runs.

Once processed, the data should scale irrespective of the 2theta. If they don't they might be indexed differently, but pointless would fix this.
