I am working with a dataset that I believe to be P21 even though the beta angle is 89.9. I picked the rfree set with phenix and expected it to pick the set in the orthorhombic set, because use_lattice_symmetry= True is the default. But the log file did not reflect that phenix recognized the almost orthorhombic symmetry. I'd like to know if it did pick the rfree set in the higher symmetry or not. thanks, Dave -- David N.
