[scipion-users] error with relion autopicking LoG

[Stefano C. <ste...@un...>]

Hi! I'm trying the relion tutorial with Scipion3. When running 
relion-autopiching LoG I've got the following error:

   Protocol failed: Command ' relion_autopick  --pickname autopick 
--odir "./" --LoG --shrink 0 --lowpass 20.000  --i 
input_micrographs.star --LoG_diam_min 150.000 --LoG_diam_max 180.000 
--LoG_adjust_threshold 0.000 --LoG_upper_threshold 5.000' returned 
non-zero exit status 127.

I tried with different batch sizes in "streaming" and with single and 
multiple MPI processes, but always have the same error..
How can I fix it?
thank you

Stefano
