Lookup Table for Computing Tau Scores

Description

This dataset is generated by searching all signatures in the LINCS database against itself to obtain a background distribution of NCS values (Qref). The latter is used to compute the Tau scores of the gess_lincs method in the signatureSearch package. The Tau score compares the observed enrichment score to all others in Qref. It represents the percentage of reference queries with a lower |NCS| than |NCSq,r|, adjusted to retain the sign of NCSq,r. NCSq,r is the normalized connectivity score for signature r relative to query q. A tau of 90 indicates that only 10 percent of reference perturbations showed stronger connectivity to the query.
