How do I import CSVs to OpenChrom?

My end objective is to compare GC outputs of samples in two groups using PCA. I have bene given the data in Excel format but have saved to CSV.

Whilst I can locate CSV files through OpenChrom, they all appear blank when I do so.

Having spend a lof of time trying to find the information, I cannot find the relevant info about how my CSV (or Excel) file should be formatted for OpenChrome.

• I have columns for retention time (labelled "RT") and area (labelled "Area").
• I have tried a simple file with two columns (RT and Area) for one sample. I have also tried files with multiple samples and columns, both with and without sample no. headers. (see pictures).

Whatever option I try, the charts in OpenChrom appear completely blank. I don't know if it's the data itself, the headings, the process I'm going through, not a clue what's going on to be frank.

Lastly, I would like to apologise that this may be a basic/naiive question for the forum. I've essentially been dumped with the work of running PCAs comparing GC data sets with little to no experience in doing so.

Thank you.
