-=head1 SYNOPSIS
-
-filter_spades_output.pl - Filters contigs or scaffolds based on contig length and coverage.
-
-=head1 USAGE
-
-filter_spades_output.pl [-c|--coverage-cutoff] [-l|--length-cutoff] [-o|--filtered-out out.fasta] -t|--tab stats.tab seqs.fasta
-
-=head1 INPUT
-
-=head2 [-c|--coverage-cutoff]
-
-Mininum coverage. Contigs with lower coverage will be discarded. Default 10.
-
-=head2 [-l|--length-cutoff]
-
-Mininum coverage. Smaller ontigs will be discarded. Default 500.
-
-=head2 -t|--tab stats.tab
-
-A tabular file, with three columns: contig name, length, and coverage:
-
-NODE_1	31438	24.5116
-NODE_2	31354	2316.96
-NODE_3	26948	82.3294
-
-Such a file is produced by spades.xml. Contigs should be in the same order as in the fasta file.
-
-=head2 [-o|--filtered-out out.fasta]
-
-If specified, filtered out sequences will be written to this file.
-
-=head2 seqs.fasta
-
-Sequences in fasta format. Start of IDs must match ids in the tabular file. 
-
-=head1 OUTPUT
-
-A fasta file on stdout.

-
-Using the output of SPAdes (a fasta and a stats file, either from contigs or scaffolds), it filters the fasta files, discarding all sequences that are under a given length or under a given coverage.
-
-Typically, this is used to discard short contigs, or contaminations. To display a coverage vs. length plot, use the "SPAdes stats" tool in the same package.

-**What it does**
-
-Using the output of SPAdes (a pair of fasta file and stat file for each of the contigs and scaffolds), it produces a coverage vs. contig plot. Each dot represent a contig/scaffold. Given a coverage and a length cutoff, sequences that do not meet those criteria are shown in red. Some statistics are also given (N50, N90, median contig/scaffold length) both before and after filtering.
-
-Use the "filter SPAdes output" tool to actually filter sequences.

-**What it does**
-
-SPAdes – St. Petersburg genome assembler – is intended for both standard isolates and single-cell MDA bacteria assemblies. See http://bioinf.spbau.ru/en/spades for more details on SPAdes.
-
-This wrapper runs SPAdes 2.5.1, collects the output, and throws away all the temporary files. It also produces a tab file with contig names, length and coverage.

+=head1 SYNOPSIS
+
+filter_spades_output.pl - Filters contigs or scaffolds based on contig length and coverage.
+
+=head1 USAGE
+
+filter_spades_output.pl [-c|--coverage-cutoff] [-l|--length-cutoff] [-o|--filtered-out out.fasta] -t|--tab stats.tab seqs.fasta
+
+=head1 INPUT
+
+=head2 [-c|--coverage-cutoff]
+
+Mininum coverage. Contigs with lower coverage will be discarded. Default 10.
+
+=head2 [-l|--length-cutoff]
+
+Mininum coverage. Smaller ontigs will be discarded. Default 500.
+
+=head2 -t|--tab stats.tab
+
+A tabular file, with three columns: contig name, length, and coverage:
+
+NODE_1	31438	24.5116
+NODE_2	31354	2316.96
+NODE_3	26948	82.3294
+
+Such a file is produced by spades.xml. Contigs should be in the same order as in the fasta file.
+
+=head2 [-o|--filtered-out out.fasta]
+
+If specified, filtered out sequences will be written to this file.
+
+=head2 seqs.fasta
+
+Sequences in fasta format. Start of IDs must match ids in the tabular file. 
+
+=head1 OUTPUT
+
+A fasta file on stdout.

+**What it does**
+
+Using the output of SPAdes (a fasta and a stats file, either from contigs or scaffolds), it filters the fasta files, discarding all sequences that are under a given length or under a given coverage.
+
+Typically, this is used to discard short contigs, or contaminations. To display a coverage vs. length plot, use the "SPAdes stats" tool in the same package.

+**What it does**
+
+Using the output of SPAdes (a pair of fasta file and stat file for each of the contigs and scaffolds), it produces a coverage vs. contig plot. Each dot represent a contig/scaffold. Given a coverage and a length cutoff, sequences that do not meet those criteria are shown in red. Some statistics are also given (N50, N90, median contig/scaffold length) both before and after filtering.
+
+Use the "filter SPAdes output" tool to actually filter sequences.

+**What it does**
+
+SPAdes – St. Petersburg genome assembler – is intended for both standard isolates and single-cell MDA bacteria assemblies. See http://bioinf.spbau.ru/en/spades for more details on SPAdes.
+
+This wrapper runs SPAdes 3.0.0, collects the output, and throws away all the temporary files. It also produces a tab file with contig names, length and coverage.
