Dear JiYG, Unless the tNCS has caused processing problems, Phaser should automatically deal with tNCS and I would recommend to just give it a try. If it fails, you could try more sophisticated approaches.

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
