Q: can I use xdisp (part of denzo) to find out the beamstop position and use it for xds? | Q: can I use xdisp (part of denzo) to find out the beamstop position and use it for xds? | ||
A: | A: yes. Unfortunately, the conventions of the different data reduction programs are not the same, but there is always a simple transformation between them, like x' = y; y' = x (which often works!) or some such. The transformation may be different for different detectors. For a given detector, you can easily find the transformation out for yourself, by noting the values from xdisp and comparing them with those from [[adxv]] or [[XDS-Viewer]]. After that, you can always find the beamstop position with xdisp, and put the transformed values into XDS.INP . | ||

Q: How do you interpret the DECAY.cbf file? | Q: How do you interpret the [[DECAY.cbf]] file? | ||
A: Using XDS-Viewer: along the x direction, you find the "integration batches" (first frames to the left; last frames to the right). Along the y direction, you find the resolution ranges (bottom: low res; top: high res). The shades of gray correspond to numbers. Move the mouse across them to find the numbers which are simply the scalefactors multiplied with 1000. | A: Using [[XDS-Viewer]]: along the x direction, you find the "integration batches" (first frames to the left; last frames to the right).
