Using the same data processing work-flow for scanning mapping, sinograms can be produced from the tomographic dataset. An example is given below. The coordinates are the sample position (ss_x) and the projection angle (ss_ry).

Before tomographic reconstruction using tomopy, the rotation center may need to be find manually:

rot_cen = dt1.get_h5_attr("overall/maps", "rot_cen")
dt1.calc_tomo_from_map(attr_names=map_keys, 
                       algorithm="pml_hybrid", num_iter=100, center=rot_cen)
calc_CI(dt1, ref_key="int_cell_Iq", ref_cutoff=0.04)

Note that some tomograms (e.g. for cellulose crystallinity index, or CI) are calculated from other tomograms. There are therefore no corresponding sinograms.
