Useful mass spectrometry programs freely available on the internet.

The intention with this chapter is to give an overview of a broad range of freely available programs on the internet which are useful for analyses of mass spectrometry data. The list is by no means a full list of free proteomics tools on the net and I apologize if there are other good tools on the internet that have been missed. The presented programs should cover the needs for the most general tasks in data analysis of proteomics data and have to a limited extend been tested. The links provided in this chapter will over time become invalid. In such cases it is worth while to try a World Wide Web search using the program packages names. This will often reveal the updated links. Some of the links presented in this chapter will also be maintained at http://yass.sdu.dk.
