Error in filter_sequences_by_length.pl

[Timmywang1]

When I run the command ‘perl filter_sequences_by_length.pl -input /data/Timmy/metagenome_test/ERR1051325.fa -output /data/Timmy/plasflow/filtered_ERR1051325.fa -thresh sequence_length_threshold’

Error:

It seems that Bio::SeqIO is not installed,
And when I run the command ‘conda install -c bioconda perl -bioperl perl-getopt-long’;
Error : “usage: conda [-h] [-V] command ...
conda: error: unrecognized arguments: -bioperl perl-getopt-long”;

when I run the command ‘cpan -i Bio::Perl Getopt::longer’,
Error : “(error): Skipping Getopt::longer because I couldn't find a matching namespace.”

Hi, you had accidentally put a dash (-) before bioperl in your command.

Try this:
conda install -c bioconda perl bioperl perl-getopt-long

Hi, I have exactly the same issue, however, I'm sure I have Bio::SeqIO installed. For some reason filter_sequences_by_length.pl doesn't find it.
How can this be fixed?
Thanks
