Often data are scaled and merged in a space group that is different from the crystal space group. For example, if the crystal space group is P212121 the data are sometimes processed in space group P222. Therefore this function returns 0 for these two symbols. For some space groups this kind of ambiguity is not possible, e.g. space group P1. The corresponding return value is 2. Some symbols could be ambiguous, but are typically not used as "default" symbols by data processing programs, e.g. P3212. It is therefore more likely that these symbols are chosen on purpose. The corresponding return value is 1. This function returns None for all non-chiral space groups. The return value for chiral space groups with unusual symbols is -1. sP23 P213sP432 P4132 P4232 P4332sI23 I213s I432 I4132tF23s F432 F4132sR3:HsR32:Hs P3 P31 P32sP312 P3112 P3212sP321 P3121 P3221sP6 P61 P65 P62 P64 P63s"P622 P6122 P6522 P6222 P6422 P6322sP4 P41 P42 P43s1P422 P41212 P4212 P4122 P4322 P4222 P42212 P43212sI4 I41s I422 I4122sP222 P212121 P2221 P21212s C2221 C222s I222 I212121tF222s P121 P1211tC121tP1t tiiii˙˙˙˙N( tgroupt is_chiraltNonetsplitttypet lookup_symboltreplacetindextKeyboardInterruptt Exceptiontlen(tspace_group_infotlinet symbol_groupstsymbolt symbol_groupti((sK/public2/ftp/pub/ccp4/6.5/ccp4-6.5/lib/py2/cctbx/sgtbx/symbol_confidence.pytlevelsR    cC s0ddlm}t|jdƒƒdks1t‚t|jdƒƒdksRt‚t|jdƒƒdksst‚t|jdƒƒd ks”t‚t|jd ƒƒdksľt‚d }xWtdd ƒD]F}t|j|ƒƒ}|dk rË|dkst‚|d7}qËqËW|d ks't‚d GHdS(Ni˙˙˙˙(tsgtbxsP -1sP 1isP 2 2 21isP 2is Hall: C 1içiAtOK(iii(tcctbxRRRR tAssertionErrortxrange(RtnRtc((sK/public2/ftp/pub/ccp4/6.5/ccp4-6.5/lib/py2/cctbx/sgtbx/symbol_confidence.pyt_test8s!!!!! t__main__N(t __future__RRR t__name__(((sK/public2/ftp/pub/ccp4/6.5/ccp4-6.5/lib/py2/cctbx/sgtbx/symbol_confidence.pyts 6
