My question is about the validity of a CIF file ... I have received a file which claims to be a CIF file. The first few lines look like:
################################################## # mmCIF file created by CS Chem3D ################################################## ################################################## # sequence section # loop_ _entity_poly_seq.entity_id _entity_poly_seq.num _entity_poly_seq.mon_id [snip] Note that the first non-comment in this line is loop_ All of the other .CIF files that I have ever seen either start with data_ or _publ_ Q: Can someone who is familiar with CIF tell me whether or not it is valid to have a .CIF file that starts with the header above? (Jmol does not have a validating .cif parser. I know that iucr is *very* concerned about making sure that programs that claim to generate .cif files are valid.) Miguel
