Batch jobs and projects

Batch jobs

The Batch tab applies the same processing to many cubes at once. Input folders are searched recursively for QCLM cube files (.bin).

Batch Preprocessing : Choose an Input folder and an Output folder, then set the processing options the same way as in the Processing tab. Click Run Batch Preprocess.

Batch Index Computation : Choose an input and output folder and import an Index YAML file (see Custom indices). Pick what to export: index maps, projections and/or plots. Click Run Batch Index.

Jobs are sent to the backend first and run there. If the backend can't be reached, the job runs locally in the desktop app instead. Progress shows in the Job queue, and the queue is saved in ~/.qclm, so it survives restarts.

Projects

A project saves everything needed to reopen an analysis exactly as you left it. In the I/O tab:

• Export Project writes a folder containing:
  • Parameters.yml: session metadata, wavelengths, reference paths, processing settings, ROIs and plot settings
  • roi_0/mask.tif: the main ROI mask
  • roi_1/mask.tif: the measurement ROI mask
• Import Project reads such a folder (or one with Parameters.json) and restores the session, masks included.

Because Parameters.yml is plain text, it works well for recording exactly how a result was produced. You can keep it alongside your data or in version control.

Exporting images

Export	Produces
Export TIFF / Export RGB composite (TIFF)	Full-resolution image from the cube data, not a screenshot
Snapshot canvas (PNG)	What you currently see in the viewer
Export spectral plot (PNG), Export PNG plot	Plots
Export CSV	The underlying numbers, for use in Python, R, Excel and similar tools
