For the translated-nucleotide search of viral RNA-dependent RNA polymerase (RdRP). Also referred to "RdRP search" in the main Serratus manuscript.

- All viral GenBank protein sequences (release version 241) were aligned with diamond --ultra-sensitive against the combined
wolf18andwolf20sequences (E-value < 1e-6). These produced local alignments which contained truncated RdRP, so each RdRP-containing GenBank sequence was then re-aligned to thewolf18andwolf20collection to "trim" them towolfRdRP boundaries.

- The above algorithm was also applied to all viral GenBank nucleotide records to capture additional RdRP not annotated as such by GenBank . A region of HCV capsid protein shares similarity to HCV RdRP, sequences annotated as HCV-capsid were therefore removed. Eight novel coronavirus RdRP sequences identified in a pilot experiment were added manually. The combined RdRP sequences from the above collections were clustered (uclust) at 90% amino acid identity and the resulting representative sequences (centroids, N = 14,653) used as the
rdrp1search query.
