I would highly recommend this paper where the authors describe an alternative to arbitrary similarity cutoffs https://pubs.acs.org/doi/pdf/10.1021/ci7004498 Pat On Wed, Jul 4, 2018 at 9:31 AM Maciek Wójcikowski wrote: > Hi > > As Nils has mentioned this is fingerprint dependent. ECFP4 have

Hi As Nils has mentioned this is fingerprint dependent. ECFP4 have the significant cutoff ~0.4, see https://pubs.acs.org/doi/10.1021/ci7004498 Pozdrawiam, | Best regards, Maciek Wójcikowski mac...@wojcikowski.pl 2018-07-04 8:44 GMT+02:00 Nils Weskamp : > Dear Phuong, > > unfortunately,

Dear Phuong, unfortunately, there is no generic answer to this question since it is highly dependent on the fingerprint, the type of compounds, your specific application and also your chemical intuition. I can only recommend to test a range of different cutoff values and to see how happy you are

To whom it may concern, I was working on finding a group of possible neighbors (similar) chemicals based on Tanimoto Similarity. I am not sure what is the optimal cutoff for finding similar chemicals. I searched online and they said it is 0.85 but there are also many exceptions they mentioned
