Any standard tomography NeXus scan file, generated by GDA, stores all the images (i.e. sample projections as well as dark- and flat-field images) in a single 3-dimensional dataset located at entry1/tomo_entry/data/data, which . This combined image dataset is accompanied by another important dataset containing which contains the corresponding image-key information, located in the same file at entry1/tomo_entry/instrument/detector/image_key in the same file. The default values of NxtomoLoader's parameters have been selected to reflect this standard scenario. However, NxtomoLoader can also be used to load dark- and flat-field data from two individual NeXus datasets, if requirednecessary. This non-standard scenario can be done by modifying handled by making appropriate modifications to the default settings of the flat and dark parameters appropriately (see the table above for more details).
