A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

About

Chromosomes of all species studied so far display a variety of higher-order organizational features such as domains, loops, or compartments. Many of these structures have been characterized from the genome-wide contact maps generated by chromosome conformation capture approaches (Hi-C, ChIA-PET,…). Indeed, DNA 3D structures translate as distinct patterns visible on these maps. We developed Chromosight, an algorithm based on computer vision approaches that automatically detect and quantify any type of pattern in contact data. Chromosight detects 3 times as many patterns as existing programs, while being faster and fit to any genome, including small, compact ones. Chromosight is user-friendly and can be extended to user-provided patterns. We validated the program by applying it to a variety of chromosomal structures found in mammals.
