Chemical system to explore, e.g. Li-Co-O or Fe-Mn-Si (up to 6 elements).

Largest unit cell to keep. Also bounds the formulas explored: only formula units with at most this many atoms. Must be between 2 and 48.

Optional space-group number (1-230) to condition every formula on. Formulas the model can't write in it yield nothing. Must be between 1 and 230.

Near-hull cutoff in eV/atom: phases within it are labeled for novelty and drawn in the phase diagram. Must be between 0 and 1.

Maximum atomic fraction per element, e.g. {"O": 0.6}.

Minimum atomic fraction per element, e.g. {"Fe": 0.4}.

Optional crystal systems to restrict generation to. Matra-Genoa proposes space groups for each formula and only those in these systems are kept. Ignored when a space group is given.

Search breadth: how many formulas to explore, smallest formula units first. Stoichiometries x candidates may be at most 2,048. Must be between 1 and 200.

Search depth: structures generated and relaxed for each formula. The lowest-energy ones go on the hull. Must be between 1 and 64.
