Scripts.DatabankLib.maicos module

Wrappers for MAICoS calculations adapted to Databank needs.

• Checks if a system is suitable for maicos calculations

• Custom JSON encoder for numpy arrays

• Custom maicos analysis classes with save methods adapted to Databank needs

Scripts.DatabankLib.maicos.is_system_suitable_4_maicos(system: System) → bool

Check if the system is suitable for maicos calculations.”

Parameters:

system – Databank System object (System)

Returns:

False if system should be skipped

Scripts.DatabankLib.maicos.first_last_carbon(system: System, logger: Logger) → tuple[str, str]

Find last carbon of sn-1 tail and g3 carbon.
