Allocate one set of grid and return an associated pointer on it.
Group all allocation for set of grids, call prepare_atom_protein to load the pdbs and charges
The initialisation of sogrid must be done before
Correctly read position of reaction coordinate ( in case of flex )
Add iflex, if THIS Solute_Grid group is not flexible, assign criteria pos from rxna ( default counter for id 1 or 2 ) If Flex, read new coordinate in tmp_atom_rcriteria, to not erase pos from rxna
| pdb_filename | : name of the pdb |
| q_filename,ep_filename,ed_filename,hd_filename,lj_rep_filename,lj_filename | : name of the charge and grids |
| atom_type_name | : atom to use for lennard-jones interaction |
| epfct,edfct,hdfct,lj_rep_fct,ljfct | : multiplicative factors for the grids |
| param_analytic | : structure parameter_analytic |
| dm,dr | : translational and rotational coefficient diffusion |
| dh_rad | : radius used in Debye Hueckel interaction terms to define solute cavity |
| vol_rad | : radius used in hydrodynamic calculations to define occupied volumes |
| rep_rad | : radius used in defining soft-core repulsion in spherical crowder model |
| param_probe | : contains the different probe in param_probe |
| bool_excl_grid | : if the exclusion grid must be computed ( or read from the disk ) |
| psgrid | : pointer to sogrid to fill |
| center | : center of the protein |
| counter_grid,counter_conf | : internal counters |
| rcriter | : instance of react_criter |
| iflex | : if the solute is flexible |
| isurface | : if the surface is a surface |
| vert_excl | : when performing excluded volume checks, is rhit considered in vertical (ie z ) direction only |
| type_calc | : instance of type_calculation |
| fixed_cent | : for a surface, the centre position can be set in input, rather than from geometric centre |
| nb_lj_opt | : optional number of lennard-jones grid or atom type to read |
