*New* SPEDAS 2.00 beta 2 released (January 2017)

The next SPEDAS release, SPEDAS 2.00 beta 2, is now available. A final, fully QA-ed release will occur sometime in 2017, but we have done enough testing to be confident that the beta release is stable and functional enough to be routinely used. This release includes several new features, including the ISEE 3D visualization tool, updated plugins for ERG, IUGONET, and BARREL, and a new plugin for working with MMS data.

This version contains the source code and can be installed in a similar way to a nightly build (see below).

* SPEDAS 2.00 beta 2, IDL source code (~25 MB)

If you do not have an IDL license, you can use the SPEDAS executable files:

* SPEDAS 2.00 beta 2, Windows 64bit executable, IDL 8.4, CDF 3.6.3, Geopack 9.4 (~50 MB)
* SPEDAS 2.00 beta 2, MacOs 64bit executable, IDL 8.4, CDF 3.6.3, Geopack 9.4 (~65 MB)
* SPEDAS 2.00 beta 2, Linux 64bit executable, IDL 8.4, CDF 3.6.3, Geopack 9.4 (~65 MB)
* SPEDAS 2.00 beta 2, Linux 64bit executable, IDL 8.4, CDF 3.6.3, Geopack 7.6 (~65 MB)

If you have an IDL license

If you have an IDL software license, then download the nightly build. Check with your system administrator on how to obtain and install IDL.

Download the SPEDAS nightly build

The nightly build contains the most recent source code:

* Download the latest SPEDAS nightly build

Unzip the files you downloaded and create a new IDL project that includes these files. To start the SPEDAS GUI from the IDL command line, type: spd_gui

IDL Geopack DLM

To use the Tsyganenko Model extensions with the SPEDAS software, you need to download and install the Geopack DLM. We recommend using the 9.4 version.

* Download the IDL Geopack

Installation instructions can be found in the download page, but basically you have to copy two files into the IDL bin directory: a .dlm file and either a .so file (Linux, Mac) or a .dll file (Windows).

You can check which version of Geopack DLM you have, by typing this at the IDL command prompt: help, 'geopack', /dlm

The GEOPACK dlm files can also be downloaded here: GEOPACK dlm files

IDL CDF library

We recommend downloading and installing the most recent version (3.6.3) of the CDF library from NASA:

* Download the CDF Library

You can check which version of CDF you have, by typing this at the IDL command prompt: help, 'cdf', /dlm

The CDF dlm files can also be downloaded here: CDF dlm files

Older versions

1. You can download the source code for the SPEDAS version 1.0 release that has undergone extensive Quality assurance (QA) testing:

* Download the SPEDAS 1.0 source code, August 2014

2. For a list of previous nightly builds, see:

* The nightly builds download site


If you don't have an IDL license

SPEDAS is free software but if you do not have an IDL license, then you cannot use the IDL command line, and hence neither the SPEDAS command line tools. You can still use the SPEDAS GUI, and you have two options:

  1. Download the SPEDAS executable (see above), or
  2. Download the SPEDAS save file.

Download the SPEDAS save file, Version 2.00 beta 2, January 2017

The SPEDAS save file requires the run-time IDL Virtual Machine (VM) which has to be downloaded for free from Exelis. There are limitations using the VM compared to the full IDL.

* SPEDAS 2.00 beta 2, IDL Savefile (15 MB)

To run SPEDAS using the IDL virtual machine,

  1. start the IDL virtual machine executable
  2. click through the splash screen to get to the file selection dialog
  3. navigate to the SPEDAS installation
  4. go into the thm_gui_new directory and click on thm_gui.sav

This should bring up the main screen of the SPEDAS GUI. From this point you should be able to load, plot, and analyze data through the GUI.

Further information for loading IDL sav files can be found here: http://www.exelisvis.com/docs/StartingVirtualMachineApplication.html

Previous version: SPEDAS save file, Version 1.00, August 2014

The SPEDAS save file requires the run-time IDL Virtual Machine (VM) which has to be downloaded for free from Exelis. There are limitations using the VM compared to the full IDL.

* Download the SPEDAS 1.00 savefile (14 MB)

To run SPEDAS using the IDL virtual machine,

  1. start the IDL virtual machine executable
  2. click through the splash screen to get to the file selection dialog
  3. navigate to the SPEDAS installation
  4. go into the thm_gui_new directory and click on thm_gui.sav

This should bring up the main screen of the SPEDAS GUI. From this point you should be able to load, plot, and analyze data through the GUI.

Installation on a Mac

Newer Mac OS X versions do not include the X11 libraries. XQuartz (X11) has to be downloaded and installed, or IDL will not work. Also, you may need to install an older Java version for IDL to work properly.

MacOS Sierra

If you want to run the executable SPEDAS file on macOS 10.12 Sierra, after downloading the zip file you have to do the following:

  • Open the Finder and move the (automatically uncompressed) spedas_v_2 directory from Downloads to your Desktop.
  • Open a terminal and type the following:

cd Desktop/spedas_v_2/spd_gui
sudo xattr -r -d com.apple.quarantine spedas.app
(enter your password)
open ./spedas.app

Installation on Windows

When we update Geopack DLM or the CDF library on Windows, we have to copy files in the "Program Files\Exelis\IDL84\bin\bin.x86_64" folder. When we try to copy files into folders that reside inside Program Files, Windows 10 (and probably older Windows versions, too) will ask for administrator permission as you can see in the following image. In that case, we just have to click the button "Continue". If we are logged in as a user without administration permissions, then we either have to log in as administrator, or perhaps contact the system administrator for the PC we are using.

Running SPEDAS for the first time

The first time you run SPEDAS, please make sure that all the directories where data files will be downloaded exist and have the proper permissions (they should be writable). To do this, launch the SPEDAS GUI (using the command spd_gui) and in the File menu choose Configuration Settings. Make sure that all the directories for SPEDAS and any other missions you use exist and are writable. If you make any changes, click "Save to File" to have the new settings saved.
