On a Linux, Mac or Solaris system, put the downloaded file into a suitable directory.   Open up a terminal window and move to the appropriate directory using the unix command ‘cd’.

Next, unzip the file ( "gzip -dc filename.tar.gz” followed by “tar xvf filename.tar"), where filename is the name of the downloaded file.   [On a Mac, the unzipping steps may be done automatically when you download the program or by clicking on the filename.]

Move into the ‘frontend’ directory (“cd frontend”).  Type “./install”.

You can run structure by typing “./structure” in the ‘frontend’ directory.

Notes:

1. In order to install the frontend you will need the Java Runtime Environment (JRE Version >1.5.0). This can be downloaded for free from http://www.java.com/downloads/.

2. If you have trouble installing or running the program, try installing and running from root (i.e., type “sudo ./install” and “sudo ./structure”). You will need to use the root password.
