Dear all, Looking to get some advice on reindexing an old dataset. I recently solved a structure of reasonable resolution at ~3A in C2. I had an old dataset at 4A in P213 that I never got a MR solution with until I solved the structure of it at 3A. I've recently gone back to to this and managed to find a solution using MolRep. However, I've not been able to refine the solution to anything below an Rfree of 60. Went back to try it in P23 and also found solution, but was never able to refine it.
I had a suggestion from my boss to reindex in a different space group (I23), but I've since misplaced the original image files (terrible) and only have the .X files from HKL. I'm wondering if it's possible to reindex using either CCP4 or Phenix. I know there's a utility for it, but my understanding is poor and I'm not sure if I can go from P --> I using this program. Thanks for any input on this very dumb problem. Peter
