        my $uniprotIDref = $_[0];
        my %uniprotIDS = %{$uniprotIDref};
        my %GOAssoc;

}


This is the line it chokes on:

UniProt Q9NWU1  OXSM_HUMAN              GO:0004315      PMID:15668256   IDA    FOXSM: 3-oxoacyl-[acyl-carrier-protein] synthase, mitochondrial precursor       IPI00016637      protein taxon:9606      20060109        HGNC


And this is the error:
