Hi Agnes,

Thanks for your reply !

Regarding my dataset, I've a total of 57 .gpr files which are triplicates
(includes one dye-swap) of 19 main experiments. These 19 experiments, from
2-distinct biological subgroups (for example, file types:  B1a.gpr, B1b.gpr,
B1dyeswap.gpr, B2a.gpr, ЕЕ T1a.gpr, T1b.gpr, T1dyeswap.gprЕ.), refer to 3
.gal files.

Now, as a bigger picture, I'm actually looking for a convenient way to
normalize as well as merge these triplicates.

Any suggestion !

Cheers,

Christina
