Under   a   NEPAD   initiative,   the   Biosciences   Eastern   and   Central   Africa   (BECA)  (www.biosciencesafrica.org) was established at ILRI. BECA consists of a hub, regional nodes, and  other affiliated laboratories and partner institutes. A state of the art joint Bioinformatics Platform  (www.becabioinfo.org), whose overall goal is to provide a coherent and powerful bioinformatics  infrastructure for use by all scientists in East and central Africa. The Platform goal requires both  physical and intellectual developments that together provide researchers with access to diverse  infrastructure in a wide­area network, thereby addressing four important aspects of bioinformatics: 

1) Science: bioinformatics tools for data integration and visualization, standardization of data  formats and data analysis strategies, and distribution of analysis tasks over local­ and widearea networks are in development; 

2)  Bioinformatics Support Facility: provides assistance and custom programming to projects  and those unable to establish a bioinformatics support function intrinsic to their project due  to shortage of qualified personnel or lack of funding; 

3) Hardware Platform: provide a powerful high performance computing platform capable of  handling the largest analysis needs for projects; 

4) Bioinformatics Training for East and central African scientists: While many Web­based  tools are available to the wet­lab researcher, the Web is not well suited for tasks beyond  single­sequence annotation. Researchers need to become productive in a server­based Unix  environment with its wealth of scripting and automation tools. Even at an entry­level, this  can be an intimidating task if proper guidance is not available.

International Centre of Insect Physiology and Ecology (ICIPE): ICIPE’s research focus is on insect biology, in order to improve the wellbeing of the peoples of the  tropics through insect science. There is a commitment to utilise contemporary science in order to  limit the impact of disease vectors, and agricultural pests. The understanding of the mechanisms  associated with behaviour (e.g. attraction and repellency) is crucial. ICIPE seeks to enhance its  bioinformatics capacity in order to support data from various EST projects designed to gain insights  into the insect ecology and plant pathogen interactions though studies of metabolic pathways  associated with production of all elochemicals. 

Long­term training activities:

Kenyatta University: An introductory course in Bioinformatics is offers to MSc Biotechnology  students. This comprises of 35 hours of lectures and practicals.

University of Nairobi: A centre for Biotechnology and Bioinformatics (CEBIB), which will offer  postgraduate training (diplomas, MSc and PhD) in areas of biotechnology and bioinformatics has  recently been launched. Other universities in Kenya, including Egerton, Maseno and the Jomo Kenyatta University of  Agriculture and Technology offer introductory courses to undergraduates in biomedical sciences. In addition, under the BECA platform MSc and PhD fellowships are being made available for  Bioinformatics students. ILRI is forging links with Universities in South Africa and the United  Kingdom to provide access to courses and training material.

Centre de Biotechnology de Sfax (CBS):
Bioinformatics activity started at CBS in 2001 with the setting­up of a research and service unit of  bioinformatics. This unit currently includes one senior researcher, one engineer and four Phd  students. Activities include sequence annotation (service) and three research programs: ab initio  prediction of short eukaryote genes, statistical modelling by Bayesian networks approach of signal  transduction pathways and statistical analysis of human sequence variation data (haplotype  reconstruction and linkage disequilibrium). Activities of the Bioinformatics unit could be found at  the website: http://www.cbs.rnrt.tn/ and the research activity report is available under request to  Bioinformatics@cbs.rnrt.tn. Although the computing facilities are good, there is still a need for  trained human resources to strengthen bioinformatics capacities at CBS, particularly in structural  bioinformatics.

If you currently use a spreadsheet like Microsoft Excel for data analysis, you might be interested in taking a look at this tutorial on how to transition from Excel to R by Tony Ojeda. The tutorial explains how to use R functions in place of Excel formulas, including tools like =AVERAGE and =VLOOKUP. For the most part, it uses modern R packages to keep the R code clear and concise.

You'll likely still be using Excel as a data source, though, so you'll also want to check out this guide to importing data from Excel to R from MilanoR.

This is a short post giving steps on how to actually install R packages. Let’s suppose you want to install the ggplot2 package. Well nothing could be easier. We just fire up an R shell and type:

> install.packages("ggplot2")

In theory the package should just install, however:

• if you are using Linux and don’t have root access, this command won’t work.
• you will be asked to select your local mirror, i.e. which server should you use to download the package.

Installing packages without root access

First, you need to designate a directory where you will store the downloaded packages. On my machine, I use the directory /data/Rpackages/ After creating a package directory, to install a package we use the command:

> install.packages("ggplot2", lib="/data/Rpackages/")
> library(ggplot2, lib.loc="/data/Rpackages/")


It’s a bit of a pain having to type /data/Rpackages/ all the time. To avoid this burden,  we create a file .Renviron in our home area, and add the line R_LIBS=/data/Rpackages/ to it. This means that whenever you start R, the directory /data/Rpackages/ is added to the list of places to look for R packages and so:

> install.packages("ggplot2")
> library(ggplot2)

just works!

Setting the repository

Every time you install a R package, you are asked which repository R should use. To set the repository and avoid having to specify this at every package install, simply:

• create a file .Rprofile in your home area.
• Add the following piece of code to it:


cat(".Rprofile: Setting UK repositoryn")
r = getOption("repos") # hard code the UK repo for CRAN
r["CRAN"] = "http://cran.uk.r-project.org"
options(repos = r)
rm(r)

I have deliberately chosen Awk in the exercises as it is a language in itself and is used more often to manipulate NGS data as compared to the other command line tools such as grep, sed, perl etc. Furthermore, having a command on awk will make it easier to understand advanced tutorials such as Illumina Amplicons Processing Workflow.

In Linux, we use a shell that is a program that takes your commands from the keyboard and gives them to the operating system. Most Linux systems utilize Bourne Again SHell (bash), but there are several additional shell programs on a typical Linux system such as ksh, tcsh, and zsh. To see which shell you are using, type

[uzi@quince-srv2 ~/linuxTutorial]$ echo $SHELL

/bin/bash
