Dear colleagues, I would like to express my thanks for all of your responses. I was able to find some "reasonable" initial space group hits, and now I have to fight against divergent refinement of cell parameters, and other things, but I hope I can solve this difficulties in some time. Actually, I have tried more than half of your suggestions before, but I still learned a lot from you. I think that this community is so far the best what internet offers. ;) Many thanks again.
