Finding unique groups of values in columns

[colmoshea]

Hi,

I have a file with immunophenotypic markers and their relationship to certain blood cells.

What I need to do is search the list and pull out the groups of defining markers for each blood cell. Some of the cells have many markers, some only have one but I need to find which combinations of markers identify each cell if possible.

I have attached the file (I think!)

Thanks,
