Staden package

The Staden package is a modular sequence analysis system, originally aimed at assembling genomic contigs. Due to its flexibility, it is used for several other tasks as well. Below is the material from our Staden introduction 2006.


R is a flexible and powerful open source statistical analysis environment.
