Zhong - work on CTF and on high-res refinement

PAP - compose_transform returns negative Eulerian angles sometimes; should always return positive.

PRB from Transform class paper

PRB regarding Sidewinder

tests on model created by sidewinder:

. 1. KLH

Conclusions

. i 3D volumes in a has better resolutions (FRC) than 3D volumes in b in the initial iterations of 3D reconstructions. a is also more similiar to the published model than b. (high cross correlation value)

. ii b converges to model created in a along with the porgress of 3D refinement

. iii The published model could be applied CTF corrections. Hence, we cannot use FRC to compare the similarity between currently reconstructed two models with the published model unless we do same correction. (it is difficult, because this requires ctf parameters of particles )

. iv Sidewinder gives better initial model than random angle assignement.
