(If the space group were correct, the result of xscale_isocluster should look similar to this:

which is from a lysozyme SSX data collection performed at the SLS; outliers are labelled. In this case, the data are truely tetragonal.)


We must now investigate whether the data have lower than tetragonal symmetry.
