About The Project

FinaleToolkit (FragmentatIoN AnaLysis of cEll-free DNA Toolkit) is a package and standalone program to extract fragmentation features of cell-free DNA from paired-end sequencing data.

Citation

If you use FinaleToolkit in your research, please consider citing our paper:

Installation

Install with conda:

conda install -c bioconda -c conda-forge finaletoolkit

Or with pip:

pip install finaletoolkit

Usage

Functionality

FinaleToolkit supports the following cell-free DNA fragmentation features:

• Fragment Length
• Coverage
• End Motifs
• Motif Diversity Score
• Windowed Protection Score
• DELFI
• Cleavage Profile

Compatible File Formats

FinaleToolkit is compatible with almost any paired-end sequence data:

• Binary Alignment Map (.bam) files with an associated index file (.bam.bai).
• Compressed Reference-oriented Alignment Map (.cram) files.
• Fragment (.frag.gz) files with an associated tabix index file (.frag.gz.tbi).

Using Fragment Files

Fragment (.frag.gz) files are block-gzipped BED3+2 files with the following columns: chrom, start, stop, mapq, strand.

We encourage you to use our comprehensive database, FinaleDB, to access relevant fragment files. Learn more about FinaleDB here.
