Index Error out of bound for for axis

Hi all,

I have saw a persistent error reported by 2D classification in both v3.1.0 and v3.2.0 as shown below:
Is that related to data or as shown by other similar topics like “CTF estimation: index error”, it could be fixed? Looking forward to your suggestions, Thanks!

Hi @zjr,

Have you installed the latest patch? That patch contains a bug fix that may resolve this issue. Definitely let us know if not!


Hi Harris,

I installed the patch posted here, the program runs well under certain circumstance but I think the problem still persist, it could be bypassed by downsampling the particles to bigger pixel size/lower resolution. But I don’t think that’s a good solution.
