小中大Before you do, you should know why you do that and what you want to get!
I give a example of myself. I am in a group which working on crystallography and cryo-EM. We see the virus particals and constracted the whole virus particals, especially the surface. After that, we need to study the protein on the surface. If it have 10 proteins, then try to identify all these proteins and solve its crystal structure, after that, build the molde in cryo-EM structure. I mean, you know, we can not do all the proteins even we can determine all the genes. Protein is much more complicated than gene. But before we really started to study proteinome, we should think about what we want to know,. If you just go and see, woo, it is very hard to draw some conclusions in this area.
