backproject_voxel gives error

[olibclarke]

Hi,

When I attempt to run backproject_voxel in order to validate parsing of poses and CTF params, I get the resulting error. This is using version cryoDRGN 1.0.1.dev126+g04c4a90 as reported by cryodrgn --version.

(cryodrgn2) cryodrgn backproject_voxel ank_downsample_128.mrcs --ctf ank_ctf_fixed.pkl --poses ank_pose_fixed.pkl --ind ank_downsample_20k.pkl -o test_reconstruct.mrc

I have used backproject_voxel without error, but I never tried it with the --ind option. Do you also get an error without this option?

Yes, I thought that might be the issue too, but saw the same error without this flag.
