Use the THOR Spectral Library Builder to build spectral libraries in the Metadata Rich Spectral Library (MRSL) format from a variety of input signature sources. The MRSL library format is specific to THOR and accommodates variable-range and variable-resolution spectra with metadata for each signature.

This workflow allows you to add, edit, or delete metadata associated with each signature.

  1. From the Toolbox, select THOR > THOR Spectral Library Builder. The Spectral Library Builder dialog appears.
  2. Import signatures.
  3. Edit metadata.
  4. Export the spectral library.
