===== sp_filterlocal =====
3D Local Filter: Locally filter maps according to the local resolution determined by [[pipeline:localres:sp_locres|sp_locres]].

\\
===== Usage =====

Usage in command line

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

\\
===== Typical usage =====

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 =====
=== Main Parameters ===
  ; 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 [[pipeline:localres:sp_locres|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)

\\
=== Advanced Parameters ===
  ; %%--%%MPI : Use MPI: (default False)
