This is a deficiency and maybe even a bug in ->set_fields(). I think ->set_fields needs more tests, as <input type="radio"> fields are not really supported by ->field or ->select.

As a workaround, the following script works for me. It uses ->field() to set the sequence and explicitly ->clicks on the radio input, because that's what the Javascript code expects to happen.

use strict;
use WWW::Mechanize::Firefox;

my $url   = "http://tools.immuneepitope.org/tools/bcell/iedb_input";
my $agent = WWW::Mechanize::Firefox->new(
    activate  => 1,
    autoclose => 0,
);

my $method = 49;
my $seq = "ARRRSFASDATRASDFSDARASDAGADFGASDRFREWFASCDSAGAREW";

$agent->get($url);
if ( $agent->success() ) {
    print "Retrieved $url\n";
    $agent->form_name('form1');
    #$agent->set_fields( 'sequence' => $seq );
    $agent->field( 'sequence' => $seq );
    my $q = sprintf '//input[@name="method" and @value="%s"]', $method
+;
    my $method_field = $agent->xpath( $q, single => 1 );
    $agent->click( $method_field, synchronize => 0 );
    #$agent->submit();
}

Update: Confirmed: ->set_fields() has a bug in it and never worked at all. The next release (0.41) will have tests and likely a somewhat more working version of ->set_fields but you should do without it for the time being. Thanks for providing such a convenient, almost self-contained example that replicates the problem.
