[ensembl-dev] Question regarding MAF

[Duarte Molha]

Hi Guys

I am retrieving variations using the API that have a certain value of MAF

for example rs770602

If you retrieve this variation

like so: $vf->minor_allele_frequency

it reports a MAF of 0.495807

but when I get each allele

my @alleles = @{$vf->get_all_Alleles};

and I cycle through them, their frequency is undef

foreach my $a (@alleles){
my $freq = $a->frequency();
print  $freq;
}

How do I retrieve the frequency calculated for each individual alleles on
the variation?

Many thanks

Duarte
