I would also be grateful if someone could help with the methods for the pairwise comparison or post hoc test for a combined experiment in a statistical software.
Dear Prof. Raiesi,
If you have several groups for example 4 groups as A B C D. You should compare A with B, A with C, A with D, then B with C, B with D and Finally C with D. This analysis could perform by ANova test with spss software or grafpad prism. Of course you can do it with tukey pairwise test that this test is a complementary test for ANova test.
Best Wishes
Amin
