Introduction

The processing perspective is designed to allow sequences of processing steps to be built and applied to stacks of data, in batch, across multiple files.

Currently processing is limited to processing data as images or vectors (spectra, powder patterns etc), either as a single dataset or as a section of a larger multi-dimensional dataset, with or without axes.

A brief introduction to the processing perspective can be found in the quick start guide.

In this guide, we use one of the examples from the quick start guide, an FTIR image of a cell sample, available to download from here:

This is a nice example file because it can be processed either as images (images of the cell at different wavelengths) or spectra (full IR spectra per pixel of the image).

Loading Data

The easiest way to load data into the processing perspective is using the File/Open... menu.

If no data is loaded, a dialog will appear allowing you to select which dataset to process, and how to process it (as image, or line, all the data, or just a subset).

If there is already data loaded, any new files must have a dataset with the same name as that selected to process, and it must have the same rank (if "dataset1" is a 3D dataset in the loaded file, any subsequently loaded files must have "dataset1" and it must also be 3D).
