Hi Juha, Hi Serban,

I was trying to perform a localised reconstruction on my virus particles
based off of the mini-tutorial on the wiki. I ran the program with the
follwoing parameters:

scipion run relion_localized_reconstruction.py
Refine3D/job015/run_ct3_data.star --prepare_particles --create_subparticles
--extract_subparticles --sym I1 --vector 0.000,0.618,1.000 --length 80
--angpix 1.065 --particle_size 350 --subparticle_size 80  --j 8 --np 4
--output Particles

while the program sucessfully created a Particles folder with several
thousand mrc files it exited with the follwoing error:

Creating subparticles...
~~~~** Running command: relion_refine --sym I1 --print_symmetry_ops --o ./
> relion_symops.tmp
The following errors were encountered upon command-line parsing:
ERROR: Argument --i not found or invalid argument
ERROR:
Errors encountered on the command line (see above), exiting...

status 1

I tried to rerun the program with a --create_star flag, but it seems this
function has been deprecated in the latest version of the program.
Could you please help me with figuring out how i can work around this error?

Cheers,
Pranav
