He should wait until Tuesday to enter data, since Y-Search is converting to
new nomenclature today.
He should ignore the instructions for SMGF, unless he specified SMGF as the
laboratory before the latest nomenclature update or has very old results.
When a user selects a lab, the results are automatically converted. He
would do the conversion for the lab he selected. FTDNA and Y-Search will
have the same standards after the conversion.
The safest thing to do is to go to SMGF, select the appropriate lab
standard, enter the data, search, and adjust any mismatching markers. If he
is 17 or less on DYS452, he should select Relative Genetics. If he is high,
select Ancestry. If he is high (17 - 26) at Y-GATA-H4, he will need to
subtract 9 or 10. Once all markers match, return to the search page and
select FTDNA as the lab. The markers will then be in the correct order for
entry into Y-Search.
