the CNS script gives the Rfree and Rcryst shellwise, and not cumulative over 
the range, i want it to be like 100  - 4.0, 100 -3.8 etc.
can the same be done in CNS!
thanx for the help!

M. Shah


the CNS script model_stats.inp does the job. See -> input files -> model_stats.inp

Best regards, Daniel
