Compound-standard mixture SB, LC-MS acquisition SB1 (paper 7.6)
phalaena:sample:PA-S-7-6-sb1
One Thermo .raw LC-MS acquisition (SB1.raw) from the Li 2018 compound-standard benchmark deposit (MetaboLights MTBLS733): one injection of standard mixture SB, which holds the same 1,100 compounds as mixture SA, 970 of them at the same concentration. The deposit's sample table lists the file as Piper nigrum seed, but the black pepper extract belongs to a separate experiment of the same study (silent-failures preprint, Table S1). The known composition makes it a benchmark dataset whose feature space is partly known. We use this file as one of two acquisitions in the validation slice. Because it is a Thermo .raw, the file routes through the RAW_TO_MZML ThermoRawFileParser stage to indexed mzML before the feature-finding chain, exercising a conversion branch the three Wave-2 metabolomics papers all skipped. This acquisition reported 44,668 features in the run's summary/summary.json.
