-''potfit'' prints information on the minimization progress to the standard output. Additionally all input and output files used are also written to standard output.

-=== Final potential ===+=====  Potfit Output Files  =====
  
-''potfit'' always writes the potential achieved in minimization to a file using the same format as for the input potential. The name of this file is specified by the [[:Category:Parameters|endpot parameter]].+====  Binned distribution file  ====
  
-=== Temporary Potential File ===+Only available for tabulated potentials: 
 +When compiled with the ''bindist'' option, a [[bindistfile]] can be created.
  
-Every now and then, depending on the algorithm used, an intermediate potential is written to a [[Tempfile|tempfile]].+====  Error report  ====
  
-=== IMD Potential File ===+At the very end of a //potfit// run there will be an [[output::errors|error report]].

-=== Plotting files ===+//potfit// always writes the potential achieved in minimization to a file using the same format as for the input potential. The name of this file is specified by the [[:parameters|endpot parameter]].
  
-Two files can generated to be used with gnuplot:  +====  IMD Potential File  ====
-* The [[Plotfile|plotfile]] is always created +

-=== LAMMPS potential file ===+If ''write_lammps'' is set to ''1'' in the [[:parameters|parameter file]], //potfit// will write a potential file for [[http://lammps.sandia.gov/|LAMMPS]]. This feature does not work for all potentials, for details see [[lammps|LAMMPS]].

-=== Dist file ===+If the ''output_prefix'' parameter is set in the configuration file, //potfit// will write several files, else all information will be printed to standard output.\\ 
 +In detail the files written are:
  
-For tabulated potentials: +''output_prefix.force'' contains the calculated and reference forces\\ 
-When compiled with <tt>dist</tt> option, a [[Distfile|distfile]] will be created.+''output_prefix.energy'' contains the calculated and reference energies\\ 
 +''output_prefix.stress'' contains the calculated and reference stresses\\ 
 +''output_prefix.punish'' contains the different punishments (EAM only)\\ 
 +''output_prefix.rho_loc'' local electron density (EAM only)
  
-=== Output files ===+All these files contain header lines, describing the following data.
