Next Generation Sequencing - Data Analysis
We provide support/services for sequence assembly, mapping (e.g., Illumina on 454 transcriptomes), contig annotation, cluster-analysis, phylogenenetic placement, metagenome / -transcriptome functional comparative analysis, ...
arb
arb is a software environment primarily for ribosomal DNA sequence data, used by several working groups at the AWI. The bioinformatics group provides a platform and user support concerning arb.
Some arb links:
- The arb project
- The Microbial Genomics Group at the MPI Bremen
- The SILVA database
Course material (7.3.2007):
- Power Point slides
- pdf version of the arb manual (from download.arb-home.de/documentation/arb.ps)
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
