General Presentation
| The TopMod package enables the calculation of the ELF function on a 3-dimensional grid, the assignment of the basins and the calculation of the basin populations and of their variance. It uses wave functions written in a wfn file which is available as output file generated by Gaussian92/94/98/03 and GAMESS ab initio softwares. The modules are written in FORTRAN 90 in order to enable dynamic memory allocation. |
In order to carry out a standard ELF analysis three programs have to be run in the following order:
- grid09: calculates ELF on a 3-D grid parallel to the standard axis defined in the MO calculation (this allows to exploit the factorization of the gaussian functions),
- bas09: assigns the grid points to basins,
- pop09: calculates the basin populations and variances.
The other modules do the following tasks:
- top_sym: exploits abelian symmetry operations,
- search09: localizes the critical points of the ELF gradient field,
- mod_wfn: enables to remove atoms in the case of large systems in order to focuss the calculation on the region of interest,
- sym_wfn: symmetrizes the wfn file for 2Π states of linear molecules,
- bas_to_syn: assigns basin types from bas.sbf file,
- sbf_to_cube: converts sbf files to cube files for Molekel,
- sbf_to_am: converts sbf files to iam files for Amira,
- wfn_to_line: generates a wireframe, stick or ball and stick molecular skeletons for Amira.
- basin_prob: computes the probabilities of having ν electrons in given basins or group of basins.
