Notice of RetractionWebpage Development for Genome Compression Technique

This is web based project which mainly deals with GENOMIC COMPRESSION. Here we have used several compression techniques i,e Huffman Compression Techniques, Four base to single base compression techniques..etc for compressing Nucleotide sequence of huge size. There are two phases one is ADMINISTRATOR and another NORMAL USER. ADMINISTRATOR handles the data and maintains the database. Initially our aim to generate the encoded file for a particular file at runtime and the signature of that particular file are stored in another file to identify that particular file while decoding but we were not able to generate at runtime but rather we store the encoded file along with signature file in the database and while retrieving decoded data from encoded data we use encoded data file along with the signature file. The DNA sequences storing and transmitting them may require a huge amount of space. This web page are help to reduce the space for storing and transmitting data, also introduce one new techniques along with exiting Huffman Technique of compression routine. DNA and RNA sequences can be considered as tests over a four letter alphabet, namely {a, t, g and c}. This algorithm can approach a compression rate of 2.1 bits /base and even lower. We tested the program on standard benchmark data used. The greatest advantage of this program is fast execution, small memory occupation and easy implementation.
