 * `sign3` [Signatures type 3](#signatures-type-3): Network embedding of observed *and* inferred similarity networks. Their added value, compared to signatures type 2, is that they can be derived for virtually *any* molecule in *any* dataset. :warning: These signatures are not calculated yet, and won't be in the near future.

 * `sims*` [Similarity vectors](#similarity-vectors): Full similarities stored as light `int8` data. Each molecule receives one such similarity vector per dataset. They may be observed (`_obs`) or predicted (`_prd`) similarities. These signatures are [only applicable to exemplary datasets](production-phase). Currently, we only keep `sims1`.
