Helical process

Hi,

I’ m very new to helical processing. In my case, filament tracer does’ work. But I can use template picker to do it.

Then I can get some good 2D.

Then, I used helical refinement to generate a initial model and tried to find symmetry parameters using symmetry search. It seems the twist and rise can not find correctly because the optimization converged to edgepoints and if I use the parameters which is the best, the resolution also can not push.

However, it seems ab-initial also can not work well.

Thanks in advance!
