Hi ccp4 guys

 I have a crystal whose spacegroup is I4,and the cell dimension are a=b=83£¬while ,the C axis is 315.SO the diffraction data is very bad when the crystal started to rotate to some degree ,and it is difficult to process the data .So I wondering there any strategy to resolve this kind of situation ,or any software to merge different crystal data together to process or phasing ?  thanks a lot for your suggestions !!!
