Okay, I'm going to presume you want to search the data.. to retrieve similar compounds or substructures. If not then just store the hexadecimal fingerprint.
It's not impossible to do searching in MongoDB, see a talk from Matt Swain <https://matt-swain.com/blog/2014-06-03-chemical-similarity-search-in-mongodb>, ... and my follow ups: http://efficientbits.blogspot.com/2014/11/memory-mapped-fingerprint-index-part-i.html , http://efficientbits.blogspot.com/2014/12/memory-mapped-fingerprint-index-part-ii.html . However my view is (as I make clear in those blog posts) MongoDB is the wrong technology for this, but you could convert your the binary fingerprint to a vector. In fact to *toString* works well: System.out.println(new > Fingerprinter().getBitFingerprint(mol).asBitSet().toString()); {43, 46, 51, 60, 65, 70, 72, 86, 95, 99, 111, 114, 123, 128, 144, 157, 158, 161, 166, 174, 185, 188, 204, 213, 222, 253, 271, 275, 278, 311, 315, 320, 335, 364, 371, 379, 390, 409, 446, 449, 463, 486, 498, 520, 523, 535, 540, 565, 574, 586, 588, 611, 628, 632, 637, 647, 649, 655, 667, 725, 742, 756, 770, 793, 845, 859, 865, 918, 951, 954, 959, 1015} You could then use and/or queries to find fingerprint subsets or computer Tanimotos etc. John On Mon, 24 Feb 2020 at 13:44, Maria Sorokina <maria.ssorok...@gmail.com> wrote: > I see the problem. > > Well, originally, I wanted to checkout how the raw fingerprints look like. > I am storing all the data (and the fingerprints) in MongoDB, and I am still > not sure if in case I save the BitFingerprints directly in there (with is > possible when the field has an Object type), if they will be parseable by > the mongo engine as fingerprints (without retrieving them to be read with > CDK).
