In DAWN 2.2 it is possible to link datasets from multiple different files into one "virtual" dataset by creating a simple linking text file. For example this could be used to generate a 4D dataset from a grid scan of an imaging detector that collects a single tiff at each point (virtual dataset shape would be [scan y, scan x, tiff size y, tiff size x]) or combining multiple line scans in HDF files into a grid scan.
An example text file can be found below. To work, the file should have the extension .dawn.
