Hi,
It depends on the transformations you want to undertake. I did a very quick
library build about 20 years ago using SMILES strings. Just have dummy atoms
with unique letters where you want to add functional groups then just do a text
find and replace with the desired SMILES of the building block you want to add
(which can of course contain dummy atoms). Then run through OpenBabel to
generate canonical SMILES. I generated a 10 million molecule library doing this.
Cheers,
Chris
