G-4 prediction tool is a web based tool to predict the putative G quadruplex forming sequences in the nucleotide sequences.
Users have two options to enter the query sequence either i) by manually entry of the sequences.
ii) Or by uploading the sequences file directly from the directory in FASTA file format or in text file format.
This program simultaneously searches the putative G-quadruplex in both sense and antisense strands of query sequences.
