# [EMBOSS tools for sequence analysis](http://www.ebi.ac.uk/Tools/emboss/)
###### Official [EMBOSS tutorial](http://emboss.sourceforge.net/docs/emboss_tutorial/emboss_tutorial.html) written by [Gary Williams](http://emboss.sourceforge.net/docs/emboss_tutorial/node8.html)
Why EMBOSS?
- Open source
- Wide range of tools for sequence analysis
- Ideal for building workflow (commandline tools)
- Accesses remote databases conveniently
The official EMBOSS suite comprises of over 150 programs that are available as commandline tools and only few of those are offered as web based applications.
Wageningen Bioinformatics Webportal, Netherlands offers [a graphical user interface to the EMBOSS suite](http://emboss.bioinformatics.nl/cgi-bin/emboss/), which we will use today for the hands-on session (more like demo!).
## Example proteins
For alignment tools, we will use human p53 and zebrafish dp53.
