Hi all i am using the Phenix-GUI first time ,for solving the sad data. I processed my raw data with the mosflm.Further output of the mosflm were used for getting other information or working through this data.so, i started with the strteiges of solve through mad. after setinmg up all the anamolous parameters ,this is always displaying red in the very first in the setup anamolous data gui with the information that format error.i used the format ccp4 unmerged i.e the direct output of the mosflm after integration.i also used the conversion of mtz file into hkl through ccp4 scaling and merging intensities-in which one option i used is the get output as unmerged intensities but, that also didnot worked. suggestions will be appreciated and also i want the deatiled information about how to use the phenix gui properly. with regards Pramod Kumar Junior Research Fellow c/o-Dr.Shekher C Mande Center for DNA Fingerprinting and Diognostics ECIL road Nacharam Hyderabad-76 -
