Error in NU-Refinement using a large box size

open

(Kacper Rogala) #1

Hello cryoSPARC Developers!

I have been using your non-uniform refinement for a couple of weeks now, and I have to say that it’s genius. Great work, guys! I’m a big fan.

It has been working for me very well until I re-extracted particles unbinned, which bumped my box size to 704 px. See the error traceback below. I saw this error discussed on the board before, but my case seems slightly different. It appears to be caused by the large box size, and for people reporting it, the crash happened right away in the first iteration, while for me it crashes later on (iteration 2…), during “Local decomposition”.

I made sure that the pixel and box sizes are identical for the starting volume and particle images. Any ideas how to go around this problem would be greatly appreciated!

Many thanks,

Kacper

Hi Guys,

I would appreciate any thoughts in dealing with this. Still unresolved!

Ali @apunjani, maybe you can help?

Cheers,

Kacper
