Can someone explain how to find for ex, 2 fold up or down regulated genes from micro array intensity data using only excel?
I think this question is basic and am new to this filed, but really want to know the calculation of 'x' fold expression from intensity dataset.
It would be helpful if you can tell me steps to do in a layman's manner.
My dataset is like,
Gene1 7.4365 8.1134
Gene2 8.6785 11.234
Gene3 9.3233 6.8965
Gene4 8.6531 14.3475
