Download alphaMELTS

The current version is 1.9 posted on August 30th, 2018

α alphaMELTS software is available in compiled executable form, for Windows, Mac OS X, and Linux. Supplementary updates of the alphamelts executable, without the ancillary files, are provided for bug-fixes and new features. A lightweight Linux VirtualBox installation of alphaMELTS provides an alternative to activating the 'Windows Subsystem for Linux' or installing the Perl program on Windows. See the list of pros and cons if you are trying to choose between WSL (Windows Subsystem for Linux) alphaMELTS, VM (virtual machine) alphaMELTS and the native Windows version.

alphaMELTS package: please log in!
Please see the *README* for a package file list, a list of changes since previous alphaMELTS versions, and checksums for downloads. To reset this page and display the WSL and VM alphaMELTS pros and cons, click the DOWNLOAD tab above.

Double-click the .zip archive to expand it and then run the installation script. For a full description of this process please see the 'Installation' section of the documentation (please right-click and choose 'Save As...' or similar) and the Operating System specific boards on the forum. It should be possible to install alphaMELTS 2 using the same procedure but substituting 'install2.command' for 'install.command', 'package' for the name of the download folder, and 'run-alphamelts.command' for 'run_alphamelts.command'; 'install2.command' will select the appropriate executable for the operating system ('alphamelts_linux' in the case of the WSL). Brief installation instructions for Windows:

First make sure MATLAB (which includes Perl), the Perl package in Anaconda, or standalone Perl is installed: for Windows users without admin access we recommend the portable version of Strawberry Perl; simply unzip the file and, optionally, move the folder to a more convenient location on your hard disk (the alphaMELTS 'install.command' script will do the required set up later).
Install the Windows Terminal (recommended): search for 'Windows Terminal' in the Microsoft Store. Selecting 'Command Prompt' from the drop down menu (the 'V' button) is the best way to run scripts like 'update.command' or 'run_alphamelts.command'.
To install the alphaMELTS package: right-click 'install.command' to choose 'Open with...' and browse to the 'perl.exe' executable (e.g. strawberry_perl_folder\perl\bin\perl.exe, or 'C:\Program Files\MATLAB\Rrelease\sys\perl\win32\bin\perl.exe’, or 'C:\Users\username\Anaconda3\Library\bin\perl.exe’). It is easiest to take the default settings for the installation script.
To update the alphamelts executable: put the 'alphamelts_win64.bin' file in the 'windows_alphamelts_1-9' folder (without renaming) and run 'update.command' by double-clicking it or by typing 'update.command' in the Command Prompt.
To install the package and update together: put the 'alphamelts_win64.bin' file in the 'windows_alphamelts_1-9' folder (without renaming) and follow the installation instructions above.
To install a pre-1-9 version of the package: download the older package from the alphaMELTS archive page and follow the installation instructions above. To install 'alphamelts_win32.exe' or, if appropriate, 'alphamelts_win32.bin', please delete or rename the 'alphamelts_win64.exe' and 'alphamelts_win64.bin' executable(s) first.

Important: the 'install.command' script may print a message that you need to set the path variable, together with brief operating-system-specific instructions on how to do this. Please do not skip this step! Most reported problems in running alphaMELTS are because the user has not set the path. The Forum FAQ have more information on setting the path (including workarounds if this is not possible).

Consult the documentation (please right-click and choose 'Save As...' or similar) to get the alphaMELTS software running correctly, including the sections on 'Setting up alphaMELTS', 'Bugs and Fixes', and 'What to do if (pH)MELTS misbehaves' (opens in a separate window). Also check the Errata and bug fixes section of the alphaMELTS support page for any temporary problems and workarounds (last updated July 4th, 2020).

Note: the alphaMELTS GitList server contains the very latest versions of the scripts and example files for alphaMELTS. Some of these files may be under development and will not necessarily work correctly with the publicly available alphamelts executable. When minor bug fixes are made to scripts or example files, between alphaMELTS releases, a link to the appropriately dated GitList version of the file(s) will be given on the alphaMELTS support page.

Mac OS X alphaMELTS is available for Intel processors only. Admin privileges are not required. The alphaMELTS 1.9 executable was built using the MacOS 10.8 (El Capitan) SDK and alphaMELTS 2 exetable was built using the MacOS 10.14 (Mojave) SDK.

Linux alphaMELTS 1.9 executables were built on Ubuntu 16.04 LTS and the alphaMELTS 2 executable was built on Ubuntu 18.04 LTS. They should run on other systems but if not please let us know, including the OS version and the output of 'gcc -v'.

WSL alphaMELTS is the recommended way to use alphaMELTS 1.X on 64-bit Windows 10 (as of v1.8), as the Linux installation includes Perl etc. WSL does require admin access for initial set up but not for updating alphaMELTS. For alphaMELTS 2 either WSL or native Windows are good options.

Windows alphaMELTS is supported on 64-bit Windows 10 only (versions for Windows 7 and/or 32-bit are available in the alphaMELTS archive). alphaMELTS mostly requires the Perl program to be installed; in version 2 it is not necessary but helpful. MATLAB contains a small Perl installation, or Perl can easily be installed via Anaconda. Otherwise, for users without admin access we recommend the portable version of Strawberry Perl 🍓

VM alphaMELTS is a lightweight Linux (64-bit and 32-bit Lubuntu) installation. It comes with the latest versions of alphaMELTS 1.9, alphaMELTS 2 (beta), and rhyolite-MELTS pre-installed. Users will need the VirtualBox program (preferably version 5.2.34 or later), which requires admin privileges for installation.
