Hello
Im trying to understand the abbreviations syn20835510 under the `Group` column within the individual data.
there's the MCI, Normal and GIS. what does GIS stand for?
thanks

many thanks for clarifying.
indeed , they are useful for re-analysis across the batches

keionn Global Internal Standard (GIS) samples are an equal weight (physical average) mixture of all protein samples in the dataset. They are used for batch correction, though there are multiple ways to use them in this regard, e.g. TAMPOR, ComBat, or ratio of other sample values / GIS on a per-protein or per-peptide basis.
