The columns are defined as follows:<br>- **mol_id**: The ligand identifier as used in the original LigBoundConf publication.- **LCSE**: The Local Conformational Strain Energy value (in kcal/mol) as reported in the original LigBoundConf publication.- **TED_torsion_energy_irrationality**: As described in the "Extended Results Tables" section.- **PoseCheck_strain_energy**: The strain energy calculated by PoseCheck (units should be specified if known, e.g., kcal/mol).<br>### GM-5K and GM-1K SubsetsThe GM-5K and GM-1K datasets represent subsets of 5,000 and 1,000 molecules, respectively, extracted from the larger collection. In addition to the original conformations, this release includes two new compressed `.sdf` archives containing conformations optimized using the MMFF94 force field: `GM-5K_mmff94_min.sdf.tar.gz` and `GM-1K_mmff94_min.sdf.tar.gz`. The molecule headers within these optimized `.sdf` files retain the identifiers corresponding to the raw conformations in the original datasets, facilitating direct comparison.<br>Detailed DFT single-point energies (for both the original and MMFF94-optimized conformations), along with HEAD analysis results, are provided in the `.csv` files `GM-1K_collection.csv` and `GM-5K_collection.csv`.<br>Besides the columns mentioned above, the other columns in the `GM-1K_collection.csv` file are explained as follows:<br>- **DFT_single_point_energy_raw**: Single-point energy (in kcal/mol) of the unoptimized raw conformation calculated using Density Functional Theory (DFT).- **DFT_single_point_energy_min**: Single-point energy (in kcal/mol) of the MMFF94-optimized conformation calculated using Density Functional Theory (DFT).- **dE**: The energy difference ($ΔE=E_{raw}−E_{opt}$) in kcal/mol, representing the change in energy upon MMFF94 optimization.- **HEAD_invalid_atoms**: A list detailing any atoms flagged as invalid by HEAD, along with the associated high-energy response value (in kcal/mol). If no invalid atoms are detected, this field contains None. For example: [(2, 'C', 40.962)] indicates that carbon atom number 2 (indexed from 1) was flagged with a high-energy response of 40.962 kcal/mol (Note: this energy value is a relative indicator and may not represent the absolute energy).- **information_entropy_label**: A binary indicator where 1 signifies an invalid conformation detected solely by the information entropy approach; otherwise, 0.<br>The `GM-5K_collection.csv` file includes all the columns mentioned above for `GM-1K_collection.csv`, as well as the following additional columns:<br>- **MM/GBSA**:The calculated binding energy (in kcal/mol) of each molecule and its binding protein using the Molecular Mechanics/Generalized Born Surface Area (MM/GBSA) method. Amber ff14SB force field is used for protien and the General Amber Force Field 2 (GAFF2) is for organic molecules.- **HEAD_E_bind**: The calculated binding energy by HEAD approach of each ligand molecule and its binding protein, unit in (kcal/mol). $E_{bind} = E^{bound}_{complex}-E^{isolated}_{protein} - E^{isolated}_{ligand}$.- **PoseCheck_num_clashes**: Number of steric clashes detected in the binding pose by PoseCheck.- **SMINA_docking_score**: The docking score of the input binding pose by SMINA software, using 'score_only' tag.- **DrugPose_score**: The calcuated simlarity score by DrugPose approach, where a higher value indicates a more similar binding pose to the reference ligand.- **DrugPose_ligand_protein_interaction_invalidity**: An indicator assessing the validity of protein-ligand interaction detected solely using DrugPose by comparing its DrugPose_score with a threshold of 50:- `0`: Valid interaction geometry.- `1`: Invalid interaction geometry.- `-1`: Not supported.<br>### DFT-5KThe conformations of DFT-5K dataset are provided in the `DFT-5K.sdf.tar.gz` archive. All molecules in this file have been optimized using the DFT method with appropriate constraints on specific dihedrals. Their single-point energies are re-calculated using a higher-level DFT method than used for optimization.<br>Each torsion fragment in DFT-5K is represented by 24 conformations, grouped under the same name in the header, corresponding to different dihedral angle values ranging from -180° to 180° in 15° increments (-180° is equivalent to 180°). Each molecule block in the `.sdf` file includes the following properties:- **TORSION_ATOMS**: Indicese of atom quartet defining the specific dihedral, starting from 0.- **DIHEDRAL_ANGLE**: The degree of the dihedral being investigated.- **DFT_SINGLE_POINT_ENERGY**: Single-point energy (in kcal/mol) calculated using DFT method.<br>In addition to the `.sdf` file, the dataset includes a `DFT-5K.csv` file containing the following columns:- **DFT_id**: The name in the header of each molecule block in `.sdf` file. Conformations with different dihedral angles of the same torsion fragment share the same DFT_id.- **xTB_dih_relative_energies**: A string of relative energies, joined by `--`, representing the energies of the conformations optimized with constraints and calculated using GFN2-xTB. The order of energies corresponds to dihedral angles from -180° to 180° in 15° increments (24 values in total). **Note**: These are relative energies, calculated by subtracting the minimum energy value among the 24 conformations, different from the single-point energies listed in previous sections.- **model_dih_relative_energies**: Similar to the above, but the relative energies are predicted by TED-Model.<br><br><br>
