to_cns w3.sca w3.hkl [< 1 second]
In this case the data extends to high enough resolution to perform Wilson scaling. This will place the data on an approximate absolute scale and is very important for the SAD phasing procedure.
cns_solve < scale.inp > scale.out [9 seconds]The output of the scale.inp task file is sad_scale.hkl, a CNS formatted reflection file. This file does contain a header which describes the data items in the file, followed by the data items themselves. The file is plain ASCII and can be viewed with any text viewer/editor. As an example, the beginning of sad_scale.hkl is shown:
