[BiO BB] drosophila affymetrix data analysis

[hz5 at njit.edu]

NP is for protein, I believe it stands for Natural Protein.
NM is mRNA, I believe it stands for Natural Mrna.
AAF is wierd, GenBank number formate is one letter and 5 number or 2 letter 
plus 6 number, like U69127 or AA002200.

Others are XP or XM, these are referenced protein and mRNA seq, generated by 
insilico approach.

I don't really know which to trust, but if you need protein sequence, you 
definitly won't use NM_, whereas is you need mRNA sequence, you definitley 
don't need NP_. I think it is depending on you research project.

NCBI has FAQs and other education materials about these topic, hehe!

Good luck!
