ERROR: particle image stack not found. Terminating...

Hi,

I ran frealign for the first time, and got this error. I converted XXX_data.star file from relion 3d autorefine by the script provided in this website. I made a image stack file by using relion_stack_create --i XXX_data.star --o XXX. I wanted to classify the particles into 4 classes so I edited the parameters file to do that. Just in case, I put the initial map XXX.mrc as an initial reference model. And I ran frealign by typing 'frealign_run_refine'. And I got this error message. "ERROR: particle parameter file not found. Terminating..." I gave some variations on parameters file as well as the environment. The stack contains more than 400k particles, and I ran it on both local workstation and cluster (slurm type). But I got the same error in both systems. Can you help me on this? Thanks a lot in advance..

Best,

Jin

p.s. attached is the m parameter file I used to run it, and the below is the first a few lines of XXX.par file made by the script
