[ensembl-dev] Problems with transcript variation adaptor

[Oliver, Gavin]

Hi, 

 

I am trying to pull variations associated with a transcript and am
having a problem whereby the transcript variation adaptor is being
flagged as 'undefined'.

 

I have tried to simplify the problem below.

 

my $registry = 'Bio::EnsEMBL::Registry';

 

$registry->load_registry_from_db(

    -host => 'ensembldb.ensembl.org',

    -user => 'anonymous',

    -port => 5306,

);

 

my $trv_adaptor = $registry->get_adaptor("human", "variation",
"transcriptvariation"); 

 

print $trv_adaptor;

 

This produces the error "Use of uninitialized value." for $trv_adaptor
in the print command.

 

Why would $trv_adaptor be undefined at this stage?
