I am interested in retrieving a DNA sequence from the GenBank database of NCBI using a perl program run in my perl 5.10 version. I searched for such perl scripts online and came across the following code (given below) as ocs5.pl. When I tried to run the code in command prompt, the perl script produced several warnings (given below). Then I tried to resolve the issue of “500 SSL negotiation failed “ after reading a few online posts. As per the online suggestions, I updated LWP::Protocol::https, IO::Socket::SSL, Net::SSLeay, OpenSSL and Bio modules from cpan (https://www.cpan.org/) inside the lib folder of Perl. The problem still persists. I seek the advice of the perl monks/experts to fix this problem.
Here goes the ocs5.pl code:
#!/usr/bin/perl use strict; use warnings; use Bio::DB::GenBank; # Create a new GenBank database object my $db = Bio::DB::GenBank->new; # Desired GenBank accession number my $accession = 'NM_000059.4'; # Retrieve the sequence object my $seq = $db->get_Seq_by_acc($accession); # Print the sequence display ID if ($seq) { print "\n Sequence ID: ", $seq->display_id, "\n"; # You can access other information like the sequence itself: print "\n Sequence: ", $seq->seq, "\n"; # To save the sequence to a FASTA file: use Bio::SeqIO; my $seq_out = Bio::SeqIO->new(-file => ">your_sequence.fasta", -f +ormat => 'fasta'); $seq_out->write_seq($seq); } else { print "\n Could not retrieve sequence for accession: $accession\n" +; } exit;
I get the following warnings after running the code:
Microsoft Windows [Version 10.0.22631.5472] (c) Microsoft Corporation. All rights reserved.

The expected output should look as follows:
