Appendix B: TT·AFM files
The TT-AFM software has three separate files that it uses. The first is a parameter file which stores all of the
parameters used for operating the microscope; The second is a scanner file, which is unique for each scanner
and has range and calibration information. Finally, data files contain images measured by the microscope.
,
B.1. Parameter Files:
When the microscope software is launched, the default parameter file is used to set all of the parameters that
are displayed on the screen. A new parameter file may be created from the default parameter file and stored
with a different name. The new parameter file can be loaded in the "Pre-Scan" window. Below is a list of all the
functions in the parameter file.
