 ## File formats
-- **The .elut file**: A **.elut** file is a TSV-like format containing raw count data from a chromatographic fractionation experiment. Each row in a **.elut** file shows the abundance of a single protein across the collected fractions (columns). Generally speaking, these fractions are collected over time. However, different chromatographic columns can separate proteins along different axes. For example, *Size-eclusion chromatography (SEC)* will mostly separate proteins into fractions according to their *size*; *Ion-exchange chromatography (IEX)* will separate them into fractions according to their *charge*. Each file in this dataset comes from one of these two column separation methods and is named accordingly ('...xx_SEC_xx...' / '...xx_IEX_xx...'. We refer to a given protein's (row's) count data across all fractions (columns) as that protein's **elution trace**. To summarize:

   - A given row contains count data for a specific protein 
   - A row's *first column* contains its associated **protein ID**
   - A row's *subsequent columns* contain that protein's count data from the fractionation experiment
