Hi @schow,
Sorry for the inconvenience- the alignments3D results are missing because they weren’t imported.
Can you clear the job, put it back in “Building” mode (by either clicking the “building” button on the job card or selecting the job, then pressing “B”, and set the Pixel Size (Angstrom) parameter? There is currently a bug in v3.1 where the pixel size isn’t read from the .star file: Relion 3.1 import - rlnImagePixelSize
