3D Local Filter: Locally filter maps according to the local resolution determined by sp_locres.

Usage in command line

sp_filterlocal.py  input_volume  locres_volume  maskfile  outputfile  --radius=PARTICLE_RADIUS  --falloff=falloff  --MPI

sp_locres exists in for both MPI and non-MPI versions.

mpirun -np 32 sp_filterlocal.py refinementdir/main002/vol0.hdf locres.hdf locfilt.hdf --radius=28 --MPI

input_volume

Input volume: Path to input volume file containing the 3D density map. (default required string)

locres_volume

Local resolution file: Path to volume file containing the local resolution estimate produced by sp_locres. (default required string)

maskfile

3D mask: Defines the region where the local filtering should be applied. (default none)

outputfile

Output volume: Path to output volume file contained locally-filtered 3D density map. (default required string)

--radius

Mask radius [Pixels]: In case no mask is provided, a hard sphere will be used. Use radius of the particle. (default -1)

--falloff

Low-pass filter fall-off [1/Pixels]: The program uses a tangent low-pass filter. Specify with absolute frequency. (default 0.1)

--MPI

Use MPI: (default False)
