Availability

HiCExplorer is available as a command line suite of tools on this GitHub repository.

A Galaxy HiCExplorer version is directly available to users at http://hicexplorer.usegalaxy.eu. Training material is available at the Galaxy Training Network, while a Galaxy Tour is available here for users not familiar with this platform. Galaxy HiCExplorer is also available as a Docker image at the Docker Galaxy HiCExplorer GitHub repository. Finally, this Galaxy version is available on the Galaxy Tool Shed and on the corresponding GitHub repository.

The following is the list of tools available in HiCExplorer

tool description
findRestSites Identifies the genomic locations of restriction sites
hicBuildMatrix Creates a Hi-C matrix using the aligned BAM files of the Hi-C sequencing reads
hicQC Plots QC measures from the output of hicBuildMatrix
hicCorrectMatrix Uses iterative correction to remove biases from a Hi-C matrix
hicFindEnrichedContacts Identifies enriched Hi-C contacts
hicCorrelate Computes and visualises the correlation of Hi-C matrices
hicFindTADs Identifies Topologically Associating Domains (TADs)
hicPCA Computes for A / B compartments the eigenvectors
hicTransform Computes a obs_exp matrix like Lieberman-Aiden (2009), a pearson correlation matrix and or a covariance matrix. These matrices can be used for plotting.
hicMergeMatrixBins Merges consecutive bins on a Hi-C matrix to reduce resolution
hicMergeTADbins Uses a BED file of domains or TAD boundaries to merge the bin counts of a Hi-C matrix.
hicPlotDistVsCounts Plot the decay in interaction frequency with distance
hicPlotMatrix Plots a Hi-C matrix as a heatmap
hicPlotTADs Plots TADs as a track that can be combined with other tracks (genes, signal, interactions)
hicPlotViewpoint A plot with the interactions around a reference point or region.
hicAggregateContacts A tool that allows plotting of aggregated Hi-C sub-matrices of a specified list of positions.
hicSumMatrices Adds Hi-C matrices of the same size
hicPlotDistVsCounts Plots distance vs. Hi-C counts of corrected data
hicExport Export matrix to text formats
hicInfo Shows information about a Hi-C matrix file (no. of bins, bin length, sum, max, min, etc)
hicCompareMatrices Computes difference or ratio between two matrices
