Supplementary dataset for Krinos et al. 2023, Missing microbial eukaryotes and misleading meta-omic conclusions, bioRxiv. Each zipped folder is a different database containing some subset of the Phaeocystis references used to map against the Tara Oceans metagenomes. These folders contain a combined database and taxonomy table derived from other sequencing dataset resources which can be used directly with the EUKulele software. `marmmetsp_all_phaeo.tar.gz` - full database including MarRef, MMETSP (Keeling et al. 2014), and all Phaeocystis references as listed in Krinos et al. (2023) `marmmetsp_all_colonies.tar.gz` - database including MarRef, MMETSP (Keeling et al. 2014), and Phaeocystis references known to form colonies (Phaeocystis antarctica, Phaeocystis pouchetii, Phaeocystis globosa) `marmmetsp_all_free.tar.gz` - database including MarRef, MMETSP (Keeling et al. 2014), and Phaeocystis references known not to form colonies (Phaeocystis rex, Phaeocystis jahnii, Phaeocystis cordata)
