Dear Vipul, At this resolution and with these Rfactors you are not supposed to „correct“ the NCS outliers. Look into the electron density maps if they are well defined and if the different conformations can be explained by e.g. crystal contacts.
However, if they are in a less well-defined region, you should superimpose the NCS symmetry molecule(s) and see which conformation would fit best and fit this conformation in the other molecules as well.

Currently the Rfree is 0.2508 and Rwork is 0.2042. My query is regarding NCS difference. Under validation tool of coot while looking for NCS differene, i can find some residues with red bar. Can some one suggest me how may i minimize it if i am expected to do it? -- Vipul Panchal Senior Research Fellow, Respiratory disease and biology, CSIR-IGIB (M)-9540113372
