We have to realize that, since the b and c axes are equal, we can index each dataset in two non-equivalent ways. This is the same situation as | We have to realize that, since the b and c axes are equal, we can index each dataset in two non-equivalent ways. This is the same situation as occurs e.g. for spacegroups P3(x) and P4(x), and means that we'll have to use a REFERENCE_DATA_SET to get the right setting for each of the 100 datasets. | ||
However, we cannot expect that all of the datasets have enough reflections in common with a given dataset. Thus, we have to update and enlarge the REFERENCE_DATA_SET after the first round, using those datasets that have reflections in common with the old REFERENCE_DATA_SET. Then in a second round, we can hopefully identify the correct setting for all datasets. After that, we can scale everything together. | |||

We choose xtal100 as the first reference, and move its XDS_ASCII.HKL to bootstrap/reference.ahkl. A script that goes through all datasets, produces XDS.INP, and runs xds is the following (note that we only REFINE(IDXREF)= ORIENTATION BEAM , and the same for REFINE(INTEGRATE), since it may be useful to keep the b and c axis exactly the same): | |||

Running this script takes 2 minutes. After this, it's a good idea to check whether the cell parameters are really what we assumed they are: | |||

Now we are ready to run our script "bootstrap.rc" a second time. Actually it would be enough to run the CORRECT step but since it only takes 2 minutes we don't bother to change the script. After this, we run xscale a third time, using the same XSCALE.INP as the first time. The result is | |||

so the data are practically complete, and actually quite good. The anomalous signal suggests that it may be possible to solve the structure from its anomalous signal. | |||
We can find out the correct spacegroup (19 !) with "pointless xdsin temp.ahkl". | |||
Now we do another round, since the completeness is so good. We can then identify those few datasets which are still not indexed in the right setting, fix those manually. It was only xtal085 which made this necessary - it turned out that the indexing had not found the correct lattice, which was fixed with STRONG_PIXEL=6. | |||
The final XSCALE.LP is then: | |||

When inspecting the list of R-factors of each of the datasets it becomes clear that some of them are really good, but others are mediocre. | |||
