Do you have any anomalous data? A Dano map may help place any anom
scatterers.
Or you could try a FFEAR search in the DELFWT map with the refined
trimer as your search model?
It has worked for me - at least once!

The resolution of the data is 2.6A. The single trimer model refines very well but only to R = 33% Rf = 35%. At this point the trimer cannot be refined anymore, it is virtually complete with few conformational violations. I understand that this second trimer is not twinned, and is probably in a state of disorder. Finding this second trimer is important, first of all to lower the R factors to an acceptable range, second of all to establish contacts between the rows of symmetry related molecules from the first trimers. When looking at the single trimer it is obvious something must fit in that region. Thanks for you help.
