Hi Jan,
I can only guess without seeing the error message. I think ending "or"
in both selection strings are the troublemakers.
Does this work:
refinement {
refine {
occupancies {
constrained_group {
selection = chain A and resseq 62 and altloc A or \
chain B and resseq 62 and altloc A
selection = chain A and resseq 62 and altloc B or \
chain B and resseq 62 and altloc B
}
}
}
}
?
