fp-tools-bio 0.2.8

_{Documentation · Output demo with ENCODE cancer cell lines · GUI demo · PyPI}

fp-tools helps you study DNA-accessibility patterns in bulk and single-cell ATAC-seq (assay for transposase-accessible chromatin using sequencing) data. It corrects sequence-related bias, scores footprints around DNA motifs, and compares signals between samples or cell groups. Results include signal tracks, tables, figures, and interactive reports. Use the command-line interface (CLI), save settings in a YAML configuration file, or use the graphical user interface (GUI).

A footprint or motif match is evidence to investigate, not proof that a specific transcription factor (TF) is bound. For CUT&Tag (cleavage under targets and tagmentation), interpret signals in the context of the targeted protein and assay controls; the ATAC-seq examples are not a CUT&Tag protocol.

Python package example:

python -m pip install --upgrade fp-tools-bio

To open the browser interface, run fp-tools-gui. See the installation guide for desktop setup and remote-server instructions. Optional de novo motif tools are downloaded automatically on first use.

Bulk ATAC-seq

bulk-footprinting runs from coordinate-sorted BAM/BAI files and matching peak BED files through the final interactive comparison report.

Prepare samples.tsv with one row per biological sample and the columns sample, condition, bam, and peaks. In comparisons.tsv, use comparison, cond1, and cond2 to name each comparison and its two conditions. The bulk workflow guide provides minimal tables and explains the required inputs.

bulk-footprinting \
  --sample-table samples.tsv \
  --comparison-table comparisons.tsv \
  --genome hg38 \
  --outdir project

The workflow uses all available cores by default. Stage progress and command messages appear live in your terminal and are also saved in the project logs.

The hg38 and mm10 labels use checksum-verified FASTA and blacklist files from the managed reference cache. A custom FASTA path and optional custom blacklist can be supplied instead. The workflow runs atac-correct, call-footprints, match-motifs, diff-footprints, and review-multi-comparisons. Each command can also be run directly. diff-footprints --comparison-axis regions compares matched genomic region sets within one sample or across biological replicates.

Optional FASTQ-to-BAM preparation is a separate prepare-atac command on the Linux CLI and in the Linux container. bulk-footprinting, the GUI, and native macOS/Windows installations start from BAM/BAI and peak BED files.

Single-cell ATAC-seq

sc-footprinting groups fragments, runs pseudobulk footprinting, and produces per-cell k-nearest-neighbor (KNN) footprint-signature heatmaps and uniform manifold approximation and projection (UMAP) views of cells.

The single-cell workflow guide provides a complete small real-data example and explains the annotation columns and AnnData count matrix required for this command. The command below is a template: replace the paths with your matched files and run from their folder.

sc-footprinting \
  --fragments fragments.tsv.gz \
  --annotations cell_annotations.tsv \
  --h5ad genomic_bin_counts.h5ad \
  --group-by cell_type \
  --genome-sizes hg38.chrom.sizes \
  --genome hg38.fa.gz \
  --peaks merged_peaks.bed \
  --outdir project/single_cell
