<div dir="ltr">Hi there<div><br></div><div>there are different ways you can go about this. If RAM isn't an issue, and some loci have more than 2 alleles, then you can use df2genind on a data.frame where alleles are coded with letters separated by a character, e.g. "a / t / a / g", or even "atag", i.e. no separator but you'll need to specify the n.char argument. </div><div><br></div><div>If RAM is an issue, genlight will let you store information on polyploids (see the tutorial on 'genomics'). The input would be a matrix of integers, each representing the number of the 2nd alleles (indiv in rows, SNPs in columns).</div><div><br></div><div>Best</div><div>Thibaut</div><div><br></div><div><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><br>--<br>Dr Thibaut Jombart<br>Lecturer, Department of Infectious Disease Epidemiology, Imperial College London<br>Head of RECON: <a href="http://repidemicsconsortium.org" target="_blank">repidemicsconsortium.org</a><br>WHO Consultant - outbreak analysis<br><a href="http://sites.google.com/site/thibautjombart/" target="_blank">sites.google.com/site/thibautjombart/</a><br>Twitter: @TeebzR<br>+44(0)20 7594 3658</div></div>
