Genome-wide extraction of reproducible continuous-valued signals hidden in noisy multisample functional genomics data

Consenrich

Consenrich is a sequential genome-wide state estimator for extraction of reproducible, spatially-resolved, epigenomic signals hidden in noisy multisample HTS data. The corresponding manuscript preprint is available on bioRxiv.

---

• Input:

  • $m \geq 1$ Sequence alignment files -t/--bam_files corresponding to each sample in a given HTS experiment
  • (Optional): $m_c = m$ control sample alignments, -c/--control_files, for each 'control' sample (e.g., ChIP-seq)
  • (Optional): wavelet-based template(s) to match for genome-wide pattern localization (--match_wavelet db<2,3,...>, sym<2,3,...>, haar, coif<1,2,...>, dmey)

• Output:

  • Genome-wide 'consensus' epigenomic state estimates and uncertainty metrics (BedGraph/BigWig)
  • (Optional) BED-like output of relative maxima in the cross-correlation with wavelet-based template(s)

Example: Consenrich outputs given 10 input ATAC-seq samples (lymphoblastoid) consenrich --bam_files ENCFF*.bam -g hg38 --match_wavelet db2 --step 25 --delta 0.50

Features

• Consenrich yields uncertainty-moderated signal tracks that effectively encompass multiple samples' epigenomic profiles $\implies$ Insightful data representation for profiling condition-specific regulatory landscapes (e.g., differential analyses).

• Consenrich resolves legitimate spatial features in epigenomic signals while attenuating noise $\implies$ Enables efficient $O(n \log n)$ genome-wide multi-sample pattern localization for deeper profiling of signal trends or to subdivide broadly enriched regions (peaks).

• Consenrich explicitly models dynamic signal trends and noise profiles for each sample with scale-invariance $\implies$ Multi-sample, multi-assay estimation of target molecular states from related functional genomics assays, e.g., ChIP-seq + CUT-N-RUN, ATAC-seq + DNase-seq.

Download/Install
