The current version of AutoDiscovery only supports Excel 97-2003 files, that is, files with XLS extension generated with any of these versions of Excel.
Unfortunately, Excel 2007 or higher files (XLSX extension) are not currently supported but these versions of Microsoft Excel will allow you to easily export your data files to the prior format. Clic here to know how to do it.
If you use other formats of information in your research project (such as images, analog signals, etc.) we suggest you to reduce them and extract the key numerical parameters from them (eg. distances between elements in the image, maximum and minimum values in the signal, etc.).
