<TITLE>Looking for help with a PCA using adegenet in R</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/plain format -->
<P><FONT SIZE=2>Hello Dr. Jombart<BR>
I was wondering if you could help me with an issue I am having with your program (Adegenet) in R.<BR>
I am attempting to perform a PCA using a structure file. The difference is that this is based on tetraploid data. Structure allows for multiple ploidy, however I am unsure of how to have the program read my data as tetraploid instead of diploid. The genetic information is for a single locus with between 2-4 alleles (with -9 representing missing data)<BR>
<BR>
Here is an example of my file (with -9 representing missing data)<BR>
<BR>
Ind Reg Al1 Al2 Al3 Al4<BR>
271 ON 7 10 11 -9<BR>
273 ON 2 10 13 -9<BR>
272 ON 4 11 12 -9<BR>
465 ON 1 2 -9 -9<BR>
472 ON 3 6 11 19<BR>
489 ON 2 3 4 19<BR>

385 ON 3 19 25 49<BR>
485 ON 7 9 12 -9<BR>
<BR>
Ind=individual<BR>
Reg=region<BR>
Al1= allele 1<BR>
Al2= allele 2<BR>
Al3= allele 3<BR>
Al4= allele 4<BR>
<BR>
<BR>
Any help would be much appreciated.<BR>
<BR>
Thank you<BR>
