Hi , I just switched to ccp4-6.1.3 and ran the phaser which is bundled with the ccp4-6.1.3 release. After molecular replacement I get a pretty good solution (TFZ 59.2) and output pdb and mtz files. I am then looking at the maps from the phaser output mtz i.e the FWT , PHWT map and the FWT PHIC map . Both maps look very crappy and look like noise. I tried the fft inside of coot and separately as a FFT inside ccp4 and these maps look bad. So the FWT PHWT calc seem to be off.
However , if I take the phaser solution output model and do the sigmaa myself. The map looks normal and sensible. It seems like phaser inside of ccp4-6.1.3 is not generating the output mtz correctly . Anyone else seeing this or is there something wrong with my setup. Hari
