So in the input-files directory, I have one massive .smi file, where each line has a SMILES string for each compound. So then in the all.ctrl file I specified the collection_folder to be …/input-files. However, when I ran VFLP I got no output. Is the problem the collection_folder parameter that I specified? Or is it the way my .smi file has been formatted (needing one file per SMILES string vs having them all in one file)?
