QGRS Mapper: a web-based server for predicting G-quadruplexes in nucleotide sequences Oleg Kikin, Lawrence D’Antonio and Paramjeet S Bagga. Nucleic Acids Research 2006 July; 34 (Web Server issue):W676-W682.
We have developed a web-based server, QGRS Mapper, that predicts quadruplex forming G-rich sequences (QGRS) in nucleotide sequences. It is a user-friendly application that provides many options for defining and studying G-quadruplexes. It performs analysis of the user provided genomic sequences...
QGRS Mapper is meant to be a flexible and comprehensive tool for investigating G-quadruplexes; hence it considers sequences with two tetrads. By default, only QGRS of maximum length of 30 bases are considered. However, the program gives the user the option ...
