ML FF NWRITE

From Vaspwiki
Jump to navigationJump to search

ML_FF_NWRITE = [integer]
Default: ML_FF_NWRITE = 1 

Description: This tag controls part of the output within the machine learning force field method.


This tag specifies the contents of the ML_LOGFILE file.

The following cases are possible:

  • ML_FF_NWRITE=1: Only information about the Bayesian errors, spilling factors and root mean square difference between predicted results and training data are output (recommended default).
  • ML_FF_NWRITE=2: All the predicted results on energy, forces and stress tensor for a given structure are written out to the ML_LOGFILE file.

A sample output should look like the following:
