Jan's Charge Analysis Code

  • installation instructions link
  • we will need a set of files
ch3oh_nbo.log (charges)
ch3oh_mk.log (charges) and ch4_mk.esp (mesh)
ch3oh_chelpg.log (charges) and ch3oh_chelpg.esp (mesh)
ch3oh_den.cub and ch3oh_esp.cub (real esp)
ch3oh.resp1in and ch3oh.resp2in (for equivalencing)
  • the general procedure will be to
generate required files, charges, density, esp g16, cubegen
visualise the fitting points for mk and chelpg fit_points.py
find resp charges antechamber, respgen then run_two-stage_resp.py, or post process charges average.py
generate new ESPs based on the charges rep_esp.py and compare ESPs field_diff.py
evaluate the fit for charges on different meshes eval_fit.py
evaluate the flexibility available for fitting esp_fit_and_flex.py
generate new esp charges modified by (the ratio of) nbo charges compromise_cli.py
additional useful information is the solvent cavity cavity.py
calculate the dipole moment of a set of charges diopole.py
