[AlvaroSmorras]

Planning of the needed tests

Cavity generation & modes

• Cavity generation with reference ligand
• Cavity generation with 2phere method
• rbcavity flags (-l, -b, -was, -ras -d, -v, -s)

Free docking with multiple protocols

• dock_free
• dock_score
• dock_minimise
• dock_solv & derivates (minimise_solv, score_solv)
• dock_pmx
• dock_htvs_filter

Docking with mandatory and optional pharmacophoric restraints, radius and types. Indirect check of ligand parsing

• dock_pharm_{acc, don, hyd, aro, any, hal, har, ani, cat}
• dock_opt_pharm

Tethered docking

• sdtether with mutiple easy and hard examples
• dock_tethered with different parameters (max_rot, max_trans, etc)
