We tested the ability of MS1-only data to identify the effects of drugs at varying concentrations on a human gut microbiome.

The microbiome was treated with either azathioprine, ciprofolxacin, diclofenac, nicatidine, paracetamol or control DMSO. Each drug was used at three different concentrations
