All, By adding m_out.adjust_column_array_sizes(len(mi)) to the bpl wrapper and defining m_out.set_n_reflections(len(mi)) in the object.h and bpl wrapper I can do what I want… I will add some tests and some warnings that this may make nonsense of the values… however before committing any comments on the interface? or behaviour?

Hi Folks,

I am trying to create a new MTZ file containing unmerged and it seems to be less simple than I would think - set_reals() on a column requires a set of Miller indices and values and does a lookup internally (which I don’t want for unmerged values) and set_values() requires that the array is already the right size - when it starts off as size 0 and I have no idea how to make enough room in there from the Python API…

Any clues? I have done quite a chunk of grepping around to try and figure this one out and have run out of ideas…
