Hi all I have one more question. Is any way in phenix GUI through which i can do phasing to lowere resolution, further phase extension to higher resolution? Becouse, my SAD data with single SeMet in whole protein of 3.5 Ang which have somewhat better phases and FOM at 5.0 ang resolution than 3.5 Ang resolution. Is it possible through phenix? If anybody have any one can help me? Thanks in advance. Pramod Kumar, c/o Dr. Shekhar C.
