-==== The geometry ==== 
  
-First of all we need the “*.bas” file of the tip and sample geometry 
-(separately). We can use the Jmol to view the “*.xyz” file. Tip should have tip 
-apex at 0.0 0.0 xy position. 
-We have even to prepare the “Fdata” of given properties of elements of tip 
-and sample we will use. 
-For followings we should run the fireball to relax these structures. If you 
-are using new FIREBALL input format, set up followings at the “fireball.in” file: 
- 
-  &OPTION 
-  basisfile = <​filename>​ 
-  lvsfile = <​filename> ​ 
-  kptpreference = <​filename>​ 
-  nstepf = 1 
- 
-Than you have the “CHARGES” of both the systems tip and sample 
- 
-

-==== The files we need ==== 
- 
- 
-We need several files before we can simulate the STM scanning for both 
-tip and sample. For sample it is “Atomo_i” with Hamiltonian of the surface and "​struc.inp"​ file with the structure informatioon,​ hopping file 
-“tip_sample_i_j.inp” (“interaction_i_j.dat”),​ “tip_e_str.inp” and “tip_g_str.inp” with 
-the densities and geometry of the tip respectively.
