Robert,
The CNS script
ncs_average_map.inp
includes a coeff (hkl,Fo,Fc,Phi) output which is of the NCS averaged
map, but it does not do iterative phase
extension.
I have written a little Jiffy to convert the coeff output from CNS
format into a XtalView phs file. I have
turned off the
CNS map output in the script - the files it creates are HUGE!
The program is available, along with an example com file at
ftp://xray.utmb.edu/pub/PMB/ pmb_NCS2phs.I65
or
http://xray.utmb.edu/ under SOFTEWARE - DOWNLOADS
Good luck, please let me know if you find the program useful.
