Supplementary Table 1
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Supplementary Table 1 The amount and percentage of contaminant sequences in the negative control that passed through quality filtering and clustered into operational taxonomic units (OTUs). The negative control contained trace contaminants from nine of the 16 mock community members. This is presumably due to cross-contamination during PCR and library preparation steps, despite surface sterilization and stringency in protocols.
