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.
