Dear RELION developers,
I am trying to expand the symmetry of the star file of my helical particles to do a further classification. I used the following command:
relion_particle_symmetry_expand --i run_data.star --helix --twist 25 --rise 21.2 --asu 1 --frac_sampling -1 --angpix 2.2
but it keeps failing, showing the following errors:
Helical: z_start= 6.95306e-310 z_stop= 6.95306e-310 z_step= 6.95306e-310

==================
ERROR:
MetaDataTable::write: cannot write to file: expanded.star
I am wondering what could be the problem?
Best,
Yangqi
