Columns 2 and 3 show the total amount of sequence information and the number of individual sequences, respectively, within each database in Column 1. Column 4 shows the numbers of sequences selected as potentially cross-hybridizing with the microarray probes. Column 5 shows the numbers of microarray probes that produced at least one hit in the corresponding CAMERA databases. Asterisks show databases with taxonomic annotations. The two databases used for taxonomic analysis of probe hits are shown in bold.
