3D Variablity Estimation: Calculate 3D variability using a set of aligned projection images as an input.
Usage in command line:
sx3dvariability.py prj_stack --ave2D=ave2D --var2D=var2D --ave3D=ave3D --var3D=var3D --img_per_grp=img_per_grp --no_norm --radius=radius --npad=npad --sym=symmetry --fl=fl --aa=aa --CTF --VERBOSE --VAR --SND --symmetrize
sx3dvariability exists only in MPI version.
mpirun -np 472 sx3dvariability.py stack --CTF --img_per_grp=100 --fl=0.25 --aa=0.1 --ave3D=vol.hdf --var3D=var_vol.hdf '''
sx3dvariability.py stack --symmetrize --sym=c2 mpirun -np 472 sx3dvariability.py bdb:sdata --CTF --img_per_grp=100 --fl=0.25 --aaf=0.1 --ave3D=vol.hdf --var3D=var_vol.hdf --sym=c2
The program calculates the variability observed in a collection of image projections. Structures with symmetry require preparing data before calculating the variability. The data preparation step would symmetrise the data and output a bdb:sdata for variability calculation. sx3dvariability.py can be slow.
