5 Minutes to Local Compute

Use this path when you want SpectraSherpa running on your own machine.

Install

pip install spectra-sherpa
spectra-sherpa

Open the local URL printed in the terminal, usually http://localhost:8000.

Add SpectroChemPy When Needed

For vendor spectroscopy files and SpectroChemPy-backed chemometrics nodes:

pip install "spectra-sherpa[scp]"
spectra-sherpa

Use this extra for workflows that depend on SpectroChemPy readers, example datasets, or algorithms.

Add HITRAN/HAPI When Needed

For HITRAN live synthesis:

pip install "spectra-sherpa[hitran]"
spectra-sherpa

You still need a HITRAN API key and egress enabled in the application settings.

First Local Workflow

  1. Open Data > Import.
  2. Upload a small CSV, JCAMP-DX, NumPy, MAT, or SpectroChemPy-enabled vendor file.
  3. Confirm file names and extensions in Files.
  4. Confirm axis and shape in Data Matrix.
  5. Open Workflows and start from a PCA or PLS template.
  6. Run the workflow and inspect the plots and metrics.

Local OSS needs no account and no cloud connection for normal local analysis.
