Just to note that sometimes Babinet solvent correction returns lower Rfree and thus may be preferred to mask (assuming that the Rfree is the only thing that matters). Beginning with 5.6.0078, you can also optimize the bulk solvent mask parameters http://www.ysbl.york.ac.uk/~garib/refmac/data/refmac_news.html#Bulk_solvent This, imho, is not likely to remove the density artifacts, but is worth a try. -- "I'd jump in myself, if I weren't so good at whistling."
