The dialog guides through the processing steps, with the option to inspect intermediate spectra and to adjust parameters.

Version 8.8: OPUS Python API

It is an interface for using OPUS functionality from Python scripts running directly within OPUS or as external scripts. The OPUS Python API offers an interface to run commands against the software OPUS to automate measurement procedures and reading spectral or imaging data. Since OPUS is available with an embedded Python interpreter a user can select and run a Python script directly from within OPUS. As an alternative, a user can communicate with OPUS using its HTTP interface. In this case your Python code is executed by your installed interpreter.

Version 8.7: New OPUS Interface for Data Evaluation using Python Scripts

The interface allows to apply data processing and evaluation methods on OPUS spectral data using Python scripts without prior data export. The results generated by the Python script can be written into and stored with the OPUS data file.

Version 8.7: New Measurement Dialog "Measure Multiple Experiments"

The "Measure" pull-down menu offers a new dialog "Measure Multiple Experiments". This dialog provides a convenient means for processing a set of experiment files (XPMs) and to merge the resulting spectra. The order of execution of individual XPMs can be selected, and for each XPM some experiment parameters can be, without having to modify the XPM-file itself. The measured spectra as well as the merge result are kept loaded in OPUS for further processing.

A typical workflow might include the following steps:

• Add one or more XPM-files to the dialog.
• Adjust the processing order of the XPM-files using the arrow buttons.
• Select any XPM from the list and adjust its experiment parameters. Parameters that do differ from the XPM-file are marked in yellow.
• Check those XPMs from the list, that shall be included in the measurement run.
• Check whether to merge the measured spectra.
• Check whether the backgrounds from some previous run of the dialog may be re-used.
• Run the measurements.
