Comment: OMERO is great. I'm just getting my feet wet but this is exactly what we need for research use (biologists, chemists, physicists, engineers, analytical imaging scientists working together). Everyone has thier favorite tools (matlab, fiji/java, python, c).

We work with n-dimensional hyperspectral data, unmixed to 32-bit analyte layers. Text is one common format we can save files to; I work in python and read these in to numpy arrays. I believe some in our group may use 32-bit floating point tiff, but some of my libraries will choke on reading in floating point image formats. So I'm testing OMERO support of text images.

To review during import testing phase.

Import has been updated for 4.4.0. As we don't have the source data or the import log files it's very difficult to be any more confident that the problem has been addressed. Closing as worksforme. If we need to re-open related tickets during the import testing phase we can. This is similar to what we've already done for #7398.
