This is a result of the following code in make_skin_map.py (the first line after the try causes the error):

        try:
            ptr_meaning = study.projectionxrayradiationdose_set.get().irradeventxraydata_set.all()[
                0].patient_table_relationship_cid.code_meaning.lower()
            if ptr_meaning in u"headfirst":
                ptr = u"H"
            elif ptr_meaning in u"feet-first":
                ptr = u"F"
            else:
                logger.info(u"Study PK {0}: Patient table relationship not recognised ({1}). "
                            u"Assuming head first.".format(study_pk, ptr_meaning))
        except AttributeError:
            logger.info(u"Study PK {0}: Patient table relationship not found. Assuming head first.".format(study_pk))

There needs to be an additional except clause for index errors.

    12ea253 Added additional except clauses to catch an error that otherwise takes place when there are no irradiation x-ray events in the study.
