| - I cannot get through a step of refinement. It always crashes and shows messages ERROR as followings. 'Error: ERROR - Bad statistics on this data set! 8 1e+20 nan multiply sizes different Mean=0.144097 Sigma=0.000000 Cut=0.072048 wt=4.000000 Error: ERROR - Bad statistics on this data set! 8 1e+20 nan Bad Sum Error: calcCCFX must have 2 images the same size Error, running 'classalign2 cls0037.lst finalref saverefs logit=2 keep=0.500000 mask=47 imask=-1 3 locfromfile ctfc=20.000000 quiet' on localhost'. I have checked size of images (iminfo), they look fine. All images have been phase corrected as well. What would possibly be the problem of this? Another question, does EMAN work on object with C11-symmetry or more? |
(and now 18 months later, I have no idea what happened :^( ) '''Q:''' I am trying to refine a structure with D7 symmetry using Eman1.8. It seemed the sym=d7 did not work at all (even one rough refinement with sym=d7 command resulted in a wrong structure). Is it a bug? Do you have any suggestion? Thank you. '''A:''' Please provide the exact 'refine' command you used (which did not work). startAny doesn't really do symmetry, and startcsym (which is what you should use) does only C7 symmetry. The idea would be to use startcsym with C7 symmetry then use proc3d to impose D7 symmetry on the final result. I think all of this is discussed in the tutorial interface if you tell it you're doing a D7 reconstruction. |

They are being converted, but it is a slow process. They should be available on the workshop page when done.
