In CONCEPT.csv (note csv normally mean comma separated whereas this file is tab separated) rows 1,354,252 and 1,355,671 have non-printable characters (\o231 and \o260 respectively) and row 1,363,867 (last row in the table ) seems to be truncated. All I see is: ‘42740714 Computed tomographic’.
Row numbers are likely to be different for others since included vocabularies may differ, the concept ids with the non-printable characters are 2101900 and 2313647.
In addition, both HL7 Administrative Sex (12) and Ethnicity (44) are not in the Vocabulary table nor are there concepts in the Concept table.
