Initial and optimized structure data

Initial and optimized structure data are saved in init_struc_data.pkl and opt_struc_data.pkl, respectively. pymatgen library is required to analyze these data files.

Data format

  • type: dict
    • key: structure ID
    • value: structure data
  • string form
    • {0: Structure Summary …,
      1: Structure Summary …,
      …}
  • structure data format

How to access

import pickle
with open('init_struc_data.pkl', 'rb') as f:
   init_struc_data = pickle.load(f)
with open('opt_struc_data.pkl', 'rb') as f:
   opt_struc_data = pickle.load(f)

# struc_step_data[ID]
#
#

# ---------- structure step data of ID 0
cid = 0      # ID
init_struc_data[cid]    # to show initial structure of ID 0

Result data

Common result data such as space group, energies, etc. are saved in rslt_data.pkl. pandas library is required to analyze this data file.

Data format

  • type: pandas.core.frame.DataFrame
    • row lable: structure ID
  • string form
    • see blow

How to access

import pickle
with open('rslt_data.pkl', 'rb') as f:
   rslt_data = pickle.load(f)


# ---------- sort by Energy
# top 5
rslt_data.sort_values(by=['E_eV_atom']).head(5)
