gcMapExplorer 1.0.11

A platform to visualize and analyze genome contact maps

Genome Contact Map Explorer - gcMapExplorer

It is a platform to visualize and analyze the contact maps that are generated from Hi-C experiments. This package is developed by considering the huge size of contact maps at very fine resolution. It contains

  • Graphical user interface - Several windows like applications to perform tasks (See below tables).
  • Command Line Interface - Several commands to perform tasks (See below tables).
  • Application Programming Interface - It can be used to perform analysis by any mathematical operations through programming.

  • Support for huge contact maps - Use of Disk instead of RAM - Matrices/arrays are stored in Disks - mathematical operations by directly reading/writing from/to Disks, without loading them into RAM

  • A browser with rich interfaces for Comparative and Interactive visualization of two dimensional contact maps along with genomic datasets such as produced by DNase-seq, ChIP-seq, RNA-seq etc.

  • Contact maps can be zoomed in/out from finest resolution to whole chromosome level.

  • Rich customizations of color scale for contact maps visualization

  • Rich customizations of X- and Y- axis properties.

  • Normalization of contact maps by
    • Iterative Correction (IC)
    • Knight-Ruiz Matrix Balancing (KR)
    • Distance-Frequency
  • A new file format based on HDF5 for genome contact map and genomic track datasets.
    • Portable, platform independent and can be read through C/C++, JAVA, Python and R programming language.
    • Very fast to read - fast browsing of contact maps and genomic datasets
  • Another file format for chormosomal contact map - much faster than above format to read/write but not compact. Suitable for performing calculations.

  • A GUI interface and commands to convert Coordinate Sparse, Pair Coordinate Sparse, HOMER Interaction matrix, Bin-Contact formats into the new gcmap and ccmap formats.

  • Interface and commands to convert bigWig/wig/bed file to genomic track dataset h5 file.

  • Interface and commands for Normalization of contact maps.

  • Publication ready images at one click.
