==== The Linear STM ====

The linear scanning gives us the current profile from the A point to the B point at constant height of the tip. To run this kind of scan we need to change some values at the "scan.inp" and "options.inp" files.

\\

=== options.inp ===   

Here the settings is same ([The files]), just the **ICUTT** parameter we have to change to value 1. Than the scan will be linear. Other values can stay same.

\\

=== scan.inp ===

In the case of linear scan, the initial and final point should be changed maybe. But the **XMIN XMAX** or the **YMIN YMAX** will be same there. 

 \\

==== ====

Than, you can run the **STM** code for linear scan simulation.

=== Output === 

As an output, we will obtain the "scan_cut_deno.out" or "scan_cut_nden.out" file, depends on the settings (the denominator means the multiple scattering is involved and the *nden.out file is obtained). The file has the following format (there is 50 rows, the scan is from the point (0.0,0.0) to (0.0,4.1742) for the distance 3A):

0.000000    0.000000    0.000000    3.000000  0.14821E-05 \\
0.083484    0.000000    0.083484    3.000000  0.14866E-05 \\

4.174200    0.000000    4.174200    3.000000  0.14821E-05

The first column gives us the length of path of the tip over the surface from the initial point, columns 2 and 3 are the x and y coordinate of the tip, 4. is the distance between tip apex and the surface and 5. column gives us the current at the given xy position.
