I parsed the proxy reference strains provided in the flat files with

for file in $(find '/Users/joverlee/Documents/WHO CC Melb antigenic data/oneDrive flat files' -type f -name '**_flat_file.csv'); do
    csvtk cut -f 'antisera,reference antigen,reference passage' "${file}" \
        | csvtk filter2 -f '$antisera in ("SH2024e", "SH2024c", "SERAPOOLe", "SERAPOOLc")' \
        | csvtk replace -f 'reference antigen' -p '(.*\d{4})pool$' -r '$1' \
        | csvtk uniq \
        | csvtk del-header >> all_vidrl_human_sera.csv
done

csvtk add-header -n 'antisera,reference antigen,reference passage' all_vidrl_human_sera.csv \
    | csvtk summary -g 1,2 -f 3:uniq
