Güralp Systems Ltd have released version 4.5 of the "Scream" acquisition software, and version 3 of the ART strong motion analysis package.

Scream is available for both Windows (all versions from Windows 98 onwards) and Linux.  ART, however, is only available on Windows.

There are a number of changes since 4.4 and a list is available on the web site at www.guralp.com/sw/scream4.5.shtml

All users are recommended to uninstall previous versions, and install one of the downloads below.


Both the Windows and Linux versions now include the "add-ons"; PSD, sinecal, stepcal, etc. ART3 is currently only available for Windows.


You can download the installer for Windows (all versions) at http://www.guralp.com/download/scream/scream45install.exe


For Linux, there are three alternative packages: an RPM, a DEB and a TAR. You only need to use one of these, but the choice depends on the distribution of Linux that you or your customers are using. Select from the following links:

http://www.guralp.com/download/scream/scream-4.5-1.i386.rpm - You may need to use the "--nodeps" rpm option during install.

Due to the change in Matlab Compiler technology since ART2 was released, it is now necessary to have the "Matlab Component Runtime (MCR)" installed on the system for ART to run. This is a ~185Mb download, and so is NOT included in the above download link. The Windows Scream installer will detect and download the necessary files during the installation process IF you select to install ART3.


Please note that when upgrading from previous versions of Scream, the method of storing the contents of a WaveView window has changed, so there will be a one-time requirement to re-create any WaveView windows that were already open.


Please also check our web pages for installation notes http://www.guralp.com/documents/html/MAN-SWA-0001/s2.html

Running Scream on 64-bit Linux

64-bit Linux distributions have traditionally supported 32-bit applications, such as Scream, using a single 32-bit support library called i32libs. This contained 32-bit versions of most of the common shared objects (libraries). Unfortunately, it became unmanageably large and needed updating every time any of the included libraries were updated.

Modern Linux distributions have moved to a new model, known as "multiarch". Under multiarch, each library is once again a separate package and the 32-bit versions are typically distinguished by the suffix :i386.

It is, therefore, often necessary to install additional libraries in order to run Scream on 64-bit Linux platforms. The precise details vary between distributions but most will follow either the Debian/Ubuntu model or the Red Hat/Fedora/CentOS model, for which details are given below.

If the instructions below do not work for you, please contact  , even if you fix the problem yourself, so that we can expand this page for the benefit of other users.

Debian, Ubuntu and similar systems

Run the following command to install the necessary libraries:

sudo apt-get install libc6:i386 libx11-6:i386 libjpeg62:i386 libxext6:i386 libsm6:i386 libxt6:i386



Ao executar o comando acima e aparecer a seguinte mensagem "0 upgraded, 8 newly installed, 423 to remove and 8 not upgraded",

não continua a instalação, pois você poderá remover todo seu sistema. Instala cada pacote separadamente.

Red Hat, Fedora, CentOS and similar systems

On these systems, it is necessary to edit the file yum.conf to direct the system to use the multiarch system. As root, open the file in your favourite editor and add the line


then save the file.

Now run the following command, which enables the use of an additional repository:

sudo yum localinstall http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

Lastly, run the following command to install the necessary libraries:

sudo yum install glibc.i686 libX11.i686 libXext.i686 libSM.i686 libjpeg-turbo.i686 libgcc.i686
