Dear All,
Did somebody have experience to try fft has keyword fillin which causes it
to substitute Fc for Fo in nFo-mFc maps.
I am useing fillin to the value of missing F's,but, it seems to make no
difference to the overall statistics, or to maps calculated. has it really
filled? or something wrong in my code: 

if ( $fill == "/bin/true") then
cat >> $qqq << EOF
FILLIN
EOF
endif

cat >> $qqq << EOF
RESOLUTION $lores $hires
FFTSYMMETRY $fftsym
GRID $grid
XYZLIMIT $ext
RHOLIM 100.0
EOF

fft HKLIN $scr2 MAPOUT $scr3 > $logft < $qqq

set x=`grep "Rms deviation from mean density ................." $logft`
echo $x
grep -i error $logft
set sigma=`echo $x | cut -d" " -f7 | cut -c1-7`


Thanks for any reply,

best regards,
weishu
