GenPress: A Novel Dictionary Based Method to Compress DNA Data of Various Species

Abstract

There can be a data boom in the near future, due to cheaper methods make possible for everyone to keep their own DNA on their own device or on a central medical cloud. With the development of sequencing methods, we are able to get the sequences of more and more species. However the size of the human genome is about 3 GB for each person. And for other species it can be more. The need is growing for the efficient compression of these data and general compressors can not reach a satisfying result. These are not aware of the special structure of these data. There are already some algorithms tried to reach smaller and smaller rates. In this paper, we would like to present our new method to accomplish this task.
