This means that dimensions can be assigned even though a unique possibility was not found. This allows you to run sane again with different parameters on troublesome peaks. Assignments are also updated in this file. Procedure Sane follows much the same procedure one would use manually. The following filters can be used and at the moment they will be applied in the order in which they are described below.
Chemical shift is used to determine all possible assignments for each dimension.
If the existing assignments are not amongst the possibilities then a warning is printed and the assignments are ignored. The expanded list of NOEs to discard is written out at the start of the OUT file. This filter is probably most useful at the start of structure calculations when attempting to obtain a global fold. It should probably not be used towards the end of the refinement. Possibilities occurring after the cutoff has been exceeded are discarded.
