You can obtain 2D PSDF modulus by Data Process → Integral Transforms → 2D FFT and choosing Modulus as the output type. PSDF is the square of that (PSDF is not directly produced, the modulus seems better for visualization). More precisely, the PSDF is proportional to the square; the 2D FFT units are always sort of arbitrary, see the parallel discussion about PSD normalization... > 2) I have an Agilent AFM, some months ago the file format was /.spm /and > Gwyddion was able to open these files now they change their file format > to /.mi/ and I cannot open these files with Gwyddion. Gwyddion can open .mi files, at least some older files I have available. Perhaps the format has changed. > Could you solve this problem. If needed I can provide you .mi files. That's always a good start because there's not much to tell without seeing the files. If you send them by e-mail, please send them compressed, do not send giant scans and send them directly to my university address [email protected].
