Mlf_refine3d_v3
Separate structurally heterogenous data sets into homogeneous classes by a multi-reference 3D-angular refinement using a maximum-likelihood(ML) target function.
Parameters
$: Metadata or stack with input images $`--nref <int`1> $`--ref <reference_file`> $`--oroot <rootname`mlf2d> $
: Also check mirror image of each reference $--thr <N
1> $--iem <blocks
1> $--no_ctf <pixel_size
1> $--ang <float
10>
ML additional options: $--eps <float
5e-5> $--iter <int
25> $--psi_step <float
5.> $--noise <float
1> $--offset <float
3.> $--frac <docfile
> $-C <double
1e-12> $: Kick-start the fast algorithm from all-zero offsets $
: Do not re-estimate the standard deviation in the pixel noise $: Do not re-estimate the standard deviation in the origin offsets $
: Do not re-estimate the model fractions $--student <df
6> =: Use t-distributed instead of Gaussian model for the noise df Degrees of freedom for the t-distribution
: Refined normalization parameters for each particle $: Save memory A(deprecated) $
: Save memory B(deprecated) $--search_shift <int
3> $--reduce_snr <factor
1> $: Use this if the experimental images have not been phase flipped $
: Use this if the references (-ref) are not CTF-deconvoluted $--limit_resolution <first_high
