 === 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):

+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.
