[adegenet-forum] Help : DAPC and Supplementary individuals

Hi there,

the variables are alleles here, not only markers. To ensure that your datasets have the same alleles, use the function repool to merge the two datasets, run the DAPC on the chosen subset, and then use the rest as supplementary individuals.

Makes sense?

Dear all,
I first performed a DAPC on a worlwide dataset genotyped using 8 microsat loci. Then I tried to inject in this analysis supplementary individuals , genotyped with all same 8 loci. The error message says that "the number of variables does not match original data". The loci are the same in both datasets, can anyone help me find what is going wrong ?
