Dear Charles,BLEND assumes data to be continuous sweeps, i.e. they should not include gaps. A valid data set,for example, could go from image 1 to image 100; an invalid one from 1 to 20 and, say, 22 to 100 - forsome reason image 21 has gone missing. This can be annoying, I know, and, indeed, a future version of BLEND will eliminate this feature. A typical case where datasets include gaps is when they are collected with the "inverse beam"strategy. In this case one should use programs like "rebatch" (keyword REJECT) on two identicalcopies of each dataset and eliminate in turn one wedge from them. There could be other reasons why files are rejected, but I need to look at one of your datasets to get moredetails. J Dr James Foadi PhD Membrane Protein Laboratory Diamond Light Source Ltd.

Do you guys have some suggestions on what could be wrong with the datasets? I processed these datasets in the same way, XDS and then POINTLESS. I am looking the detail of the processing. Meanwhile, I would like to know what others could make these datasets invalid as judged by BLEND. I have tried to use the XDS_ASCII.HKL, the same invalid datasets. Thanks!
