This page provides instructions for downloading and installing the Free Trial Version of Datasqueeze for Linux. You may run this version for up to ten days before purchasing a registered version. If, after downloading and running the trial version, you decide you want a upgrade to the full-featured registered version, please purchase the access key-this is all you will need to make the upgrade. Datasqueeze is also available for Macintosh, Windows, or Unix-like operating systems..

Requirements

• A PC running at at least 300 MHz.
• A color monitor display resolution of at least 1024 x 768.
• At least 60 MB of available memory. Note that in some multiple-user environments the system administrator may have placed quotas on the amount of disk space and/or memory per user, so that even if the machine has enough memory you as a user may not; check with your system administrator if you are not sure.
• 10 MB of free disk space.
• The Linux operating system. This application has been tested on a limited number of platforms. There is no reason at this point to believe that it will not run on all flavors of Linux, but the level of printing support does depend on the flavor of Linux that you have.

Installing datasqueeze

• Click here to download the installation package.
• Locate where your browser downloaded the file called ds_installation.tar.gz, and change to that directory. (Some browsers may partially or completely uncompress the file, producing something called ds_installation.tar or a folder called ds_installation. If so, ignore the next couple of steps).
• Type
  gunzip ds_installation.tar.gz
  This should produce a new file called ds_installation.tar.
• type
  tar xf ds_installation.tar
  This should produce a new directory called ds_installation. Change to that directory (cd ds_installation).
• You have two options for installing the program. If you are a system administrator (superuser) you can install it in a central location so that everyone on your system can use it. If you are an ordinary user, you can install it in your home directory.
  1. For system-wide installation:
     • Type su to become superuser (you will need the superuser password). If you do not have permission to do this, talk to your system administrator before proceeding.
     • This installation assumes that the java application lives in /usr/java/bin/java. To see if this is the case, type
       ls -ls /usr/java/bin/java
       If you get something that looks reasonable, you are ready to go. Otherwise, you will need to locate Java on your system. Then edit the 5'th line of the file called ds_install_global to reflect the true location. (See comments above regarding multiple versions of Java.)
     • Type:
       sh ds_install_global
     • To start the application, type
       datasqueeze
       or
       datasqueeze file1 file2 file3 ...
       from whatever directory you might be working in.
  2. For installation as a user application (in your directory only):
     • This installation assumes that the java application lives in /usr/java/bin/java. To see if this is the case, type
       ls -ls /usr/java/bin/java
       If you get something that looks reasonable, you are ready to go. Otherwise, you will need to locate Java on your system. Then edit the 5'th line of the file called ds_install_local to reflect the true location. (See comments above regarding multiple versions of Java.)
     • Type:
       sh ds_install_local
     • To start the application, type
       /home/yourname/ds/datasqueeze
       or
       /home/yourname/ds/datasqueeze file1 file2 file3 ...
       (where yourname is your login name) from whatever directory you might be working in. Note that a new window is opened for each file, consuming memory, so you will not be able to open more than a few files at the same time.
• When you first run, you will be asked to enter an access code and to agree to some legal stuff. If you do not have an access code, you can run the Trial version, which will run for up to ten days. If, after downloading and running the trial version, you decide you want to upgrade to the full-featured registered version, please purchase the access key-this is all you will need to make the upgrade. If you have done the system-wide installation, you will need to give the access code to each potential user of the application. Note that your licence does not permit you to make Datasqueeze available to a large user base from a central server. If it is to be loaded on a central server and accessed remotely it should be only for the use of a small research group (5 users or less).
• An onboard help menu provides additional instructions--new users are strongly urged to read through the help file, which includes a short tutorial, before using the program. An onboard help menu provides additional instructions--new users are strongly urged to read through the help file, which includes a short tutorial, before using the program. Additionally, a complete manual in pdf format will be found in the program files folder (see contents).
• If Datasqueeze refuses to run at all, it is likely that your current version of Java (or at least your current default version) is too old. Go back to the instructions on installing Java on your system.
• When you have completely installed the program, you can remove the installation files:
  rm -f -r ds_installation.tar ds_installation
• If things do not initially work as you expect, check out our FAQ page or contact us.

Contents

• A file called datasqueeze_manual.pdf. This is the Manual --you could copy it anywhere convenient or print it out if you wanted.
• A file called datasqueeze.jar. This contains the compiled Java code.
• A folder called samples. Within it are:
  • Files called agbe_calib.raw and sample.raw. These are "typical" Bruker-Siemens data files for you to play with.
  • A file called agbe.std. This is a typical Bruker calibration file, for silver beheneate, which you could also use as a template.

Note on running in x-windows environment:

Installing the Java Platform

• This program was written for Java 2 Standard Edition, version 1.4.1. It should be compatible with any later version of Java. Note however that the open-source versions of Java distributed "out of the box" on some Linux systems will not work. If you are running Java 1.3 or earlier, or if your computer does not have Java 2, you need to download it, which can be done for free from the Java site. The download URL is currently http://java.sun.com/.
• You will have a choice of products to download; you want the latest version of the Java Runtime Environment (JRE).
• You will probably have to be the administrator (superuser) before you do this part.
• If you are not sure whether java has been loaded on your machine or whether it is the right version, type
  java -version
  at the command line. It should say something like
  Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)
  which in this case would indicate that you are running version 1.3.1.
• In some cases there may be multiple versions of java installed on the same computer, in which case it might be necessary to to type a different command to get the latest version. For example, on a computer which had both 1.2 and 1.4 loaded, typing
  java -version
  would return
  Solaris VM (build Solaris_JDK_1.2.2_07a, native threads, sunwjit)
  but typing
  /pkg/j/j2sdk1.4.0/bin/java -version
  might return
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
• Locating Java On Your System If just typing "java -version" does not work, your path settings do not include the location of java and/or it is located in a funny place. Look around for it. You might try typing
  find /usr -name java -a -print
  If you think you have found the application, test it out. For example, suppose that you located a copy of java in
  /usr/java/bin/java
  (This is a common location). In that case typing
  /usr/java/bin/java -version
  should give you version information.
