Overlap features search from a new list of Genomic Regions

Search for features that overlap a list of genome coordinates you enter or upload, e.g. GK000001.2:50000..100000


  • Genome regions in the following formats are accepted:
    • chromosome:start..end, e.g. GK000001.2:15000..25000
    • chromosome:start-end, e.g. GK000001.2:15000-25000
    • tab delimited
  • Both base coordinate (e.g. BLAST, GFF/GFF3) and interbase coordinate (e.g. UCSC BED, Chado) systems are supported, users need to explicitely select one. By default, the base coordinate is selected.
  • Each genome region needs to take a new line.


  1. Type/Paste in genomic regions in  base coordinate ?  interbase coordinate ?
    or Upload genomic regions from a .txt file...

  2. Extend your regions at both sides:
