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. Raji ---------Included Message---------- >Hi all >i am trying to solve a structure using MIR by solve/resolve.
