 A subset of the Q Exactive HF-X Orbitrap (Thermo Fisher) data dependent acquisition (DDA) data described by [Van Puyvelde et al., 2022](https://www.nature.com/articles/s41597-022-01216-6) was used as a benchmark dataset. Here, only the first biological replicate series (named “alpha”) was used, encompassing three technical replicates of two different conditions (referred to as “A” and “B”). The samples are a mixture of commercial peptide digest standards of the following species: Escherichia coli (P/N:186003196, Waters Corporation), Yeast (P/N: V7461, Promega) and Human (P/N: V6951, Promega), with logarithmic fold changes (log2FCs) of 0, −1 and 2 for respectively Human, Yeast and E.coli. 
 Please refer to the original publication for the full description of sample preparation and data acquisition parameters ([Van Puyvelde et al., 2022](https://www.nature.com/articles/s41597-022-01216-6)).
