Hi Vineet,
Try using TEXTAL for model building at your resolution. I heard
that this is optimized for 2.8Ang or so resolution.
For MTZ to HKL with HL's intact, read the Tutorial section on the
CNS webpage with example scripts. Go to section 'Data Conversion'
and look at 'Converting a CCP4 MTZ reflection file'.
Hope that helps.
