Hello Pranav,

as far as I know, relion2 is not supported by localrec scripts. You will have to use relion-1.4

Best regards,
Grigory

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:

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
