[Bioperl-l] MeSH term retrieval

[Michael Seewald]

Dear Bioperl-Users, dear Heikki,

I am trying to retrieve MeSH term descriptions using Bio::DB::MeSH (bioperl
v1.5.0). Sometimes it works (first example below), sometimes it does not
(second example). Is there anything wrong with the query?

Thanks & bets wishes,
Michael


use Bio::DB::MeSH;

my $mesh = new Bio::DB::MeSH();

# works, compare:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?holding=&db=MeSH&cmd=search&term=Eisenmenger%20Complex
my $term = 'Eisenmenger Complex';
print "Term: $term\n";
print "Desc: ",$mesh->get_exact_term($term)->description,"\n";

# does not work, compare:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?holding=&db=MeSH&cmd=search&term=Sinus%20Thrombosis,%20Intracranial
my $term = 'Sinus Thrombosis, Intracranial';
print "Term: $term\n";
print "Desc: ",$mesh->get_exact_term($term)->description,"\n";
