On a side note, I assume that you have searched with both P2 as well as P21 for your space group. If not, I will point out that there are 265 submissions in the rcsb for the P2 space group, compared to 20,698 for P21. That makes P2 fairly rare. Good Luck! - Todd

I processed the data to P2. But the data set has tNCS problem. I want to do molecular replacement. Is there anyone know how to deal with this problem? Thanks, JiYG
