Installing HAPPE

There easiest way to install HAPPE is to use pip3.

pip3 install HAPPE

or you can clone the project to your local directory and installing it with:

python3 setup.py install --record log.txt
#if u want to uninstall the package:
#cat log.txt | xargs rm -rf

then you should have the HAPPE command available.

$ HAPPE -h

usage: HAPPE [-h] -g CONFIG -v GZVCF [-k KEEP] [-r REGION]
                          [-s SNPLIST] -i INF -c COLOR [-I SNPINF] [-R REF]
                          [-F FUNCANN] [-f | -x | -n] [-D DEPTH] [-d DEPTHBIN]

Preparing config file

[software]
bgzip=
bcftools=
tabix=

Preparing the vcf file

1. The SNP/INDEL ID must be in the format :Chromosome_position.
2. Only bi-allelic remains in vcf file.
3. Compress vcf to vcf.gz using bgzip
4. Use bcftools index to create an index for the vcf.gz file.

Preparing the depth information

if you want to integrate the depth information, you need to prepare the depth file as follows:

1. Create a directory for each sample with the name of the sample.
2. using mosdepth to calc the depth of each position for each sample.

#example
mosdepth -f ref.fa -Q 0 sample1/sample1.Q0  path/to/sample1.bam

Usage

"-g  CONFIG", required parameter, give the paths to bcftools, bgzip and tabix in the CONFIG file. 

"-v GZVCF", required parameter, input vcf file.

"-k SAMPLELIST", required parameter, list of samples to be retained, one sample per line.

"-r REGION", optional parameter, the genomic region to be displayed, format: chromosome: start-end.

"-s VARIANTLIST", optional parameter, the list of variant IDs you need to keep, using this parameter you cannot use the -r parameter.

"-w TREEWIDTH", optional parameter, the width of the tree topology.

"-i INFORMATION", optional parameter, additional sample information, the first column must be the sample ID.

"-c COLOR", optional parameter, Specify the color of each sample, the first column is the sample id and the second column is the color hex code.

"-I VARINFORMATION", optional parameter, Additional variant annotation information, such as GWAS p-value. the first colum is the variant id and each column is the annotation information with header.

"-f", optional parameter, Only the variant that changes the amino acid is retained.( Requires that the input vcf file has been annotated with SnpEff.)

"-x", optional parameter, Only the variant in the CDS region is retained.( Requires that the input vcf file has been annotated with SnpEff.)

"-n"， optional parameter, Only the variant in the non-coding region is retained.( Requires that the input vcf file has been annotated with SnpEff.)

"-D DIRECTORY"， optional parameter, This directory contains the depth information for each sample calculated using mosdepth, one directory per sample.

"-d WINDOWSIZE", optional parameter, window size for calculate normalized depth.

"-o PREFIX"， required parameter, output prefix.
