Shell commands can be combined in scripts files that perform complex actions. In the following, a very short introduction to the csh (and tcsh) shell programming is given. For other types of shell, the reader can consult comprehensive textbooks dedicated to this argument reported in the reading list at the end of this appendix.Continue reading

Yet Another Introduction To LINUX
What is Linux?
Linux is a free and open source operative system (OS) derived from the Unix OS. It is created by Linus Torvalds. Initially, it was developed for personal computer but now it is diffused on almost all the existing computer architecture. The OS is freely available in different software distribution assembled by commercial or public companies. These distros regularly release freely available open-source Linux distributions in the form of a downloadable CD, DVD or even memory stick bootable images for the easy installation and customization. The reader is recommended to try to install her own version of Linux using one of the distributions (see a list at the end of the chapter). For scientific applications, the Scientific Linux is recommended since it is customized for the use in academic and research institutions and contains most of the open source scientific packages.
In this chapter, only a short introduction to the operative system Linux is provided. The reader is encouraged to deepen her knowledge on the topic by consulting more detailed tutorials or books guide suggested at the end of the chapter.Continue reading

Studies of preferential solvation of peptides and proteins in solution
Chemical environment (pH, salts, co-solvents) plays an important role in the stabilization of secondary structure forming peptides and proteins in solution. The presence of co-solvent in aqueous solution can increase the structural stability as well as to promote denaturation or conformational changes. Continue reading
Study of structural and dynamical properties of peptides in solutions
The recent progress on time-resolved optical spectroscopy and FRET techniques have opened new exciting perspectives to the understanding the short timescale dynamics of peptides in solution. In fact, experimental data provided by these measurements can be directly compared with the results of computer simulations. Continue reading
