The classification target is the M. tuberculosis culture result (0=NEG, 1=POS); samples with culture \"not applicable\" are dropped. Microarray spot ids (block_row_column) are mapped to M. tuberculosis ORFs (Rv locus tags) via the GPL9790 platform table; array-specific segment/alt spots (\"-s1\", \"-alt\") are collapsed to the base locus tag by averaging. Rv locus tags are mapped to UniProt accessions via the H37Rv reference proteome (UP000001584); spots that do not resolve to a UniProt accession are discarded."
