Markush Enumeration
Enumeration of generic structures • File input • Enumeration type: – Sequential – Random • Number of enumerated structures can be limited (per input structure) • Valence filter • Scaffold alignment • Markush code generation. The scaffold ID can be: – fetched from data field – generated (prefix + number)

MolConverter
“Swiss army knife” for molecular format conversion • Input and output can either be – File – Property – Pipeline Pilot Molecule • Specified input format or auto detection • Various output formats or custom format string • Option to halt or continue on error, error messages put into property • 2D cleaning (coordinate generation) only when needed (default). Unconditional 2D or 3D cleaning or no cleaning can also be selected
