The 23andMe format refers to style of a 23andMe file (tab delimited, with columns for rsid, chromosome, position, results) but not the content. The Genes for Good chip has its own set of SNPs, only some of which are found in files from FTDNA, AncestryDNA, and 23andMe. The last I heard, GEDmatch did not think there was enough overlap to be useful.
