Chapter 1 Obtaining YASARA

1.1 What is YASARA

YASARA stands for Yet Another Scientific Artificial Reality Application and allows interactive viewing, manipulation, and analysis of molecular data and models. The simplest version of YASARA, YASARA_view, is freely available via the internet at: http://www.yasara.org/viewdl.htm

For a fee, more capable versions of YASARA are available. However, the majority of this book will deal with the functions in free version of YASARA, YASARA_view.

1.2 Download YASARA_view

Visit the YASARA_view website and enter the appropriate information into the menu. If you are unsure about 32-bit or 64-bit, in Windows this information is shown by clicking on This PC in the Windows Explorer then System Properties. System Type will indicate 32-bit or 64-bit as shown in 1.1 .

Once you have submitted the information, you will receive an email which will let you download the YASARA program.

1.3 Installing YASARA

Move the YASARA program (Mac) or install package (Windows) to an appropriate folder. I have found that installing and running YASARA from the Downloads folder is not a good idea. On Macs, it seems that programs in the Downloads folder are not given read/write permission which can cause issues with running YASARA.
