 **Description** Recosntruction of a panel shift micro-CT scan of a coffee bean. The recosntructed images are 3340 x 3340 x 900 voxels, with 2134 projection of size 3780 x 900. This recosntruction is to showcase possibility of very large reconstruction using TIGRE. Reconstruction using FDK and GCLS (a very memory heavy algorithm) are shown.
