You don't say what you mean by "too high", but if you are in a space group with multiple possible indexing conventions (eg different choices for the direction of b in a polar spacegroup) you can get very high Rmerge values. In the scalepack section of the old HKL manual ( http://hkl-xray.com/hkl-manual) there is a Reindexing scenario that explains how to approach this problem; the HKL matrices can be used as macros in HKL2000.
