it takes long time to add map for the reaction.
```

```

```py
%%time
from indigo import *
indigo = Indigo()
def addmapbyINDIGO(rxnsmi):
smi = rxnsmi
rxn = indigo.loadReaction(smi)
rxn.automap('discard ignore_charges ignore_isotopes ignore_valence ignore_radicals')
# rxn.automap()

rxnsmi_map_indigo = rxn.smiles()
return rxnsmi_map_indigo

rxnsmi='CC(C)(C)c1cc(CCc2cc(CCc3cc(CO)cc(CCc4cc(CCc5cc(C(C)(C)C)cc(C(C)(C)C)c5)cc(CCc5cc(C(C)(C)C)cc(C(C)(C)C)c5)c4)c3)cc(CCc3cc(C(C)(C)C)cc(C(C)(C)C)c3)c2)cc(C(C)(C)C)c1>>CC(C)(C)c1cc(CCc2cc(CCc3cc(C=O)cc(CCc4cc(CCc5cc(C(C)(C)C)cc(C(C)(C)C)c5)cc(CCc5cc(C(C)(C)C)cc(C(C)(C)C)c5)c4)c3)cc(CCc3cc(C(C)(C)C)cc(C(C)(C)C)c3)c2)cc(C(C)(C)C)c1'
tem=addmapbyINDIGO(rxnsmi).split()[0]
print(tem)
```

when I spend RDT tools to add map, it spend less time.
