Script Error using TRAVIS.Core.pl script within TRAVIS transcriptome viral scanner

Question

[cwva]

Hi,

I'm new to bioinformatics, and I'm trying to run the TRAVIS Transcriptome virus scanner on my sequences. When running the Core script, I see this error message pop up. Is this a script error that I should report to the developers, or is this something I did to the script? I'll include the necessary details below; please let me know if there's any other information that I might need to include.

The error message:

Use of uninitialized value in concatenation (.) or string at /home/cwva226/scratch/bin/travis/TRAVIS_Core.pl.1 line 1285, <$FH_IN> line 1409252.

The line this error message is referencing:

my $crt_ORF_ID =join ('_', "$$sref_sequence_ID\_ORF", sprintf ("%03d", $number_of_ORFs)); 

I have only made one change to this script at the beginning, which is the addition of the 8th line:

#!/usr/bin/env perl
use warnings;
use strict;
use File::Path qw(make_path);
use File::Basename;
use File::Spec;
use Data::Dumper;
use lib '/home/cwva226/scratch/bin/travis/local-lib-2.000029/Parallel-Loops-0.10/lib/';
use Parallel::Loops;
no warnings 'experimental::smartmatch';

Here's a link to the entire script on github

Thank you!
