The following software must be present before installing Woland.

Perl is required to run Woland. Minimal recommended Perl version is 5.17. To check Perl version type:

$ perl -v 

Set your perl environment variable PERL5LIB for modules:

$ export PERL5LIB=/home/user/perl5/lib

Edit ~/.bashrc to include PERL5LIB variable.

You also need R in order to generate reports. Minimal recommended R version is 3.1.

Using Git, clone woland repo:

$ git clone https://github.com/tiagoantonio/woland

$ tar vxzf woland-source.1.01.tar.gz

./INSTALL [woland install folder complete path]

Perl modules:

$ cpan App::cpanminus
$ cpanm Bio::DB::Fasta
$ cpanm Cwd
$ cpanm List::Util
$ cpanm IPC::System::Simple
$ cpanm IPC::Run
$ cpanm Parallel::ForkManager
$ cpanm Regexp::Common
$ cpanm Text::Balanced
(Text::Balanced version should be higher than 1.97)
$ cpanm Text::Wrap
$ cpanm Statistics::R
$ cpanm Moo
$ cpanm Getopt::ArgParse
$ cpanm List::MoreUtils

R packages:

$ R
$R install.packages("reshape2")
$R install.packages("ggplot2")
$R install.packages("qqman")
$R install.packages("RColorBrewer")
$R install.packages("plyr")
$R install.packages("gtools")
$R q();

Woland needs genome reference sequence and its gene annotation for each organism. User should download two files in order to perform its analysis.

Download genome reference sequence, move to genomes/ folder and rename it (if necessary):

$ mv hg19.fa woland/genomes/hg19.fa

Download annotation, move to genomes/ folder and rename it:

$ wget http://hgdownload.cse.ucsc.edu/goldenPath/hg19/database/refGene.txt.gz
$ gunzip refGene.txt.gz
$ mv refGene.txt woland/genomes/refseq_hg19.txt

Woland.batch enables batch submission of multiple samples as provided by input.table file. This script runs woland-anno.pl for each sample followed by woland-report.pl generating one result folder for each sample file provided and a grouped report folder for whole analysis as provided by input.table:

$ woland-batch.pl -i <input.table file> -c <chromosome.profile file> -g <genomes.folder> -n <genome.version> -r <refseq.file> -w <hotspot.window length> -t <number.of.threads> -o <target.output folder>

• -i input.table file: Path for a regular tabular file without header. First column is group name. Second column is file sample name of annovar annotated.variant file. Samples files MUST be located in the woland folder .

• -c chromosome.profile file: Path for a regular tabular file without header . First column is chromosome name in chr format (e.g. chr13). Second column is chromosome length sequenced. Useful for targeted-enrichment sequencing projects. User can build this file with target .BED file using woland-bed.pl.

• -g genomes.folder: Path for genome folder where FASTA sequences are located.

• -n genome.version: Genome version of genomes.folder/[genome.version].fa and genomes/refseq_[genome.version].txt files.

• -r refseq.file: Complete path and file of refseq annotation.

• -w hotspot.window: A natural number N (N>1), for hotspot window length. Hotspot window corresponds to N nucleotides flanking each SNV.

• -t number.of.threads: Default is 30.

$ perl woland-batch.pl -i input.table.tgca.csv -c profiles/chromosome.profile.hg19.bed.exons.txt -w 1000 -g genomes/ -n hg19 -r genomes/refseq_hg19.txt -o .

• woland-bed.pl

This script generates a <chromosome_profile> file using a bed file from a targeted-sequencing experiment. The <chromosome_profile> file is used in other Woland scripts.

$ perl woland-bed.pl -b <bed-file>

• woland-isectoannovar.pl

Use woland-isectoannovar to perform multiple intersections between VCF files from ** HUMAN EXOME** resequencing experiments to select private variants and annotate them using ANNOVAR.

$ perl woland-isectoannovar.pl -c <type of change> -f <vcf files> -a <annovar folder path> -l <HTSLib/VCFTools folder path> -t <number of threads>

• woland-anno.pl

woland-anno.pl uses a single annovar.variant_function file to calculate all patterns in a single result folder for annovar.variant_function file provided.

$ perl woland-batch.pl -i <annovar.variant_function> -c <chromosome.profile file> -g <genomes.folder> -n <genome.version> -r <refseq.file> -w <hotspot.window length> -o <target.output folder>

• woland-report.pl

This script uses a group of samples to perform woland-anno.pl script for each sample provided to build an unique grouped report output folder for the analysis. Sample names and groups are provided by <input.table> and one result folder is also generated for each sample provided.

$ perl woland-report.pl -i <input.table file>

• woland-mutageniclogo.pl

Use woland-mutageniclogo.pl to extract stranded context sequences FASTA files specific for C>T, G>T and G>C changes AFTER woland-report. For more details please read README,

$ perl woland-mutageniclogo.pl -s <type of 5'3' change> -i <input.table file>

• results-samplename folder : All results from a single sample file.
• report-samplename folder : Grouped report files [.txt] and graphic reports from a single [input.table].
