I would like to see this feature "return" as well. Pete.

Hi, Alex's answer is pretty much correct. What you might find is that there are some advanced controls in the different software that affect the results you get, such as bandwidth control, filters, etc. I actually asked this question of a few different vendors, and they tend to do it slightly differently, but Alex's answer is a good one. Make

Hi Zhuoyang, This is extremely easy to avoid in the nanoscope software. In the "flatten" filter dialog, either use the "threshold" command, or simply draw boxes around the raised features to exclude from the flattening algorithm. Regards, Pete.

Hi Luci, I guess you mean that you are trying to identify magnetic fields associated with this iron, because of course there are much better ways than MFM to detect iron! I am also assuming that you have already checked that the material is magnetic with magnetometry. If you have such large crystals of magnetic material, and it's actually magnetised

If I remember correctly, this problem in version 5 is overcome by OPENING the files in the analysis part of the online software (i.e. on the machine you collected them on). After this, they can be moved elsewhere and analysed. Gosh, I remember the fun of opening 100´s of forces curves, one at at a time in the DOS program... I don't know if

Stephan, Well, perhaps you are right, I have no experience with the ICON...but I have tried to do multiple lift mode images over a single nanoparticle with a (nonlinearised) multimode, and I can assure you that it's challenging! (but possible!) One of the main issues with lift mode for MFM is that the "magnetic" and "topographic"

Hi Monique, for images with "steps" i.e. terraced samples, the best results are often obtained with plane fitting to ONE of the terraces. This is actually discussed in chapter 5 of my book "Atomic Force Microscopy" by Eaton and West. The chapter may help you a lot with image processing. If you show us the image s before and after

Hi Luci, This sounds pretty difficult. Due to many problems, one of which could be drift in z, I think using lift mode on a sample with 300nm features will be very difficult. If you think about the way lift mode works, it's based on the idea that the magnetic fields will be propagating (more or less) vertically from the surface. If your sample has

HI dalia, I dont knwo how to do it in version 6.13 NS software. The way I do it is open the image in Gwyddion,and use the "Metadata browser" (in "Meta" menu), and look there, the data is displayed alphabetically, and there's a LOT of it in nanoscope files, but you can also save it to a text file for searching! Pete.

Dear Zhouyang, I do not have experience on the innova, but I do have some experience with membrane proteins. IN general, it is more likely that sample perparation/scanning optimisation is hampering your results than the inherent capabilities of the instrument. I would be fairly certain that the isntrumetn has the resolution required. How are you scanning
