AssertionError for 3D Homogeneous Refinement

When trying to perform a homogeneous consensus reconstruction, i get an assertion error with this result: assert ctf_params.shape == (Nimg, 8)

I used this command: cryodrgn abinit_homo /home/earlab/Desktop/jdgf/krish/particles.128.mrcs --ctf /home/earlab/Desktop/jdgf/krish/ctf_particles.pkl -o /home/earlab/Desktop/jdgf/krish >> con_rec.log

I expected it to run for 30 epochs and refine the particles but was met with this error

How do I fix this? Is there a problem with my ctf parameters?
