Hi, just to make sure: The Omicron MATRIX stores the image data in a .mtrx file, but for opening them correctly, the _0001.mtrx session file has also to be present in the same directory. The omicronmatrix plugin automatically searches for this file and parses it, it contains all dimensions.
If it is not found, a comment will be included in the Data Browser next to each image as a warning, please check this. If the _0001 file is not found, the module falls back to map the raw data along the z axis - this might easily end up in km as the raw data is the int ADC value or such. If the _0001 file is present, no comment is in the Data Browser and the problem persists, please send the file in question (and also the corresponding _0001 file) to me, I'll have a look at it.
