These pages contains link to the benchmarks for the different CASToR. Each benchmark consists in a dataset and a reference image that is a reconstruction of this dataset. A script (provided for both Unix and Windows systems) can be used to reconstruct the dataset with your own CASToR installation and check the consistency between the reconstructed image and the reference image. The consistency check is performed by a program that analyzes the differences of voxels' values and sends a warning when beyond a preset value.
These benchmarks can be a good starting point to have a quick look at the input file formats as well as the available options.
