Search Lattice

Syntax: iplt_diff search [-f] [-i MASK] [-v VERB]

Searches for a lattice in the raw diffraction pattern, using a zero knowledge approach. This is a thin wrapper around the LatticeSearch class in the ex module.

Parameters in project.xml

Under the group LatticeSearch:

  • GaussFilterStrength: size of initial gaussian filter to apply prior to peaksearch, a value of 0 disables this pre-filtering
  • PeakSearchSensitivity: initial sensitivity value to determine which pixels are identified as peaks during peaksearch, will be adjusted during the algorithms 
<DiffProcessing>
  <LatticeSearch>
    <GaussFilterStrength value="1.0" type="float"/>
    <PeakSearchSensitivity value="0.004" type="float/>
  </LatticeSearch>
</DiffProcessing>

Results in info.xml

Under the group DiffProcessingResults/DiffSearch/

  • the found lattice as a Lattice group
