'''KLH'''  . a 3D reconstruction in /mnt/shared/prbTestKLH/TEST_1/REFI15 KLH single particle 3D reconstruction, which uses KLH-100-class-averages-refined sidewinder model as the reference model . b 3D reconstruction in /mnt/shared/prbTestKLH/TEST_2/REFI15 KLH single particle 3D reconstruction, which uses KLH-100-class-averages-refined randomly-assigned-angles model as the reference model'''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 progress 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. .
