you should find a new EXPERIMENTAL version of gwyddion that opens the topography files properly, and much faster than the manual version. You can also see them in the browser window now!
The next "official" release of Gwyddion should also support the other channels.

Gwyddion is the "recommended" program. I have a little procedure to open them with Gwyddion, and I am sharing it below. Let me know if there are any problems with this. Hopefully we will have a more efficient (binary) format soon!

Open Saved Data File with Gwyddion

1. This procedure is to open files with the extension .wsf from version 1.4.1 or 1.5.1 of AFM Workshop software.
2. Use Gwyddion 2.20 or later
3. Click file ->open
4. Navigate to the directory. For 1.5.1, the files are located in a directory specified in Testdata_path  in the parameter file.
5. Select File Type:Raw Data files, select the file and click open.
6. In the information tab, select the resolution and physical dimensions as specified in the file name.
7. Under z scale the correct setting is normally 1.00 nm, for the left image, and 1.00 mV for the right images.
8. Tn change the units click “change” and type the name of the unit you want to use. You may then need to click the drop down list of units to refine it (i.e. to change from mm to nm).
9. In the data format tab, select Text data, and start form line: 17. Leave row skip at 0 lines. Field delimiter should be set to “any whitespace”. I t is a good idea to go into presets, and save this configuration under a name like “AFMWORKSHOP 1.5.1 128 pix”.
10. Click OK.
11. NOTE: Opening files like this takes a LONG TIME if they are of a high resolution..To give an idea, on the Dell inspirons with sempron processors, approximately the following times apply:

 If anyone can open these files with another package, please post the details here. Gwyddion is actually slower at opening these files than it should be,  although once they are open, the program is great, and you can save them as another format once there.

If somebody need the Gwyddion's users manual in pdf format, this link can help.

http://surfnet.dl.sourceforge.net/project/gwyddion/user-guide/2009-11-11/gwyddion-user-guide-en-2009-11-11.pdf

I think this user manual can be better with deeper information.

It can be an option so that the customer is not limited to just the 50 micron scanner. Making it an option will keep the initial cost down but for those who want to purchase a smaller (or larger) scanner later, they may do.

The system looks modular enough to allow for this.

Any other ideas on this?

Also, does anyone have any enclosures they would recommend for the TT-AFM?

The probe mounting setup is quite nice, with the space provided to "rest" the chip before sliding it in. The problem I have is getting it into the right place after that. Do people grip the probe substrate at the side while sliding? There is not a lot of room for this. At the moment, i tend to drag it with the tweezer point on the back of the substrate.

From my experience of using lots of different systems, there is always a "learning" period while you break many chips getting them in before you figure it out...pete.

students need something which pushes forward their imagination....
