Sounds then like your spacegroup is p321... It's your data (scaling) that determines that, not your preconceptions (which wasn't clear how arrived at either?)

Scaling the data for MAD experiments, the number of rejections and chi2 values were very high even after adjusting the error-scale factor and error model. The space group i used was p312 which i obtained by running a self-rotation function in MOLREP. When i scale my data using p312 spacegroup the chi2 and rejections were huge. But he data was scaling well in p321 spacegroup. can anyone explain whats going on? Thank you very much Deepthi
