The last two are needed to specify the axis type (q/2 theta/d/pixel), and perform any intensity correction.

from uk.ac.diamond.scisoft.analysis.io import NexusDiffractionMetaReaderNexusDiffractionCalibrationReader as NexusMetaReader |
With these imports a basic integration can be performed with the following lines of code:

readermeta = NexusMetaReader.getDiffractionMetadataFromNexus(r"Path/To/Your/Calibration/File.nxs") meta = reader.getDiffractionMetadataFromNexus(None) if (not reader.isPartialRead()): sys.exit("no metadata in file") ,None) #Load image data data = dnp.io.load(r"Path/To/Your/Data.tiff")['image_name'][...] #Create object to do integration [In this case pixel split](metadata, then number of bins) integrator = PSI(meta, 2000) #integrator = NPSI(meta, 2000) #integrator = PSI2D(meta, 2000, 360) #integrator.setAxisType(axis.ANGLE) ### # 1D Azimuthal ### #For full image, integrating azimuthally, in q only need to call out = integrator.integrate(data._jdataset()) #out[0] is axis, out[1] is intensity dnp.plot.line(out[0],out[1], name="Plot 1", title = "Full Image - non split") |
Other options can be explored using methods on the integrator object or in the PixelIntegrationUtils class.
