Pros of VM alphaMELTS versus the native Windows version:

Cons of VM alphaMELTS versus the native Windows version:

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 October 14th, 2016).

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.


Linux logoLinux alphaMELTS is available for 32-bit and 64-bit architectures. The executables were built on Ubuntu 14.04 LTS (llvm 3.4). They should run on other systems but if not please let us know, including the OS version and the output of 'gcc -v'.

OS X logoMac OS X alphaMELTS is available for Intel processors only.

Windows logoWindows alphaMELTS requires the Perl program to be installed. MATLAB contains a small Perl installation, or for users without admin access we recommend the portable version of Strawberry Perl.

VirtualBox logoVM alphaMELTS is a lightweight Linux (Lubuntu 32-bit) installation that will be of most use to Windows users. It comes with the latest versions of alphaMELTS and rhyolite-MELTS pre-installed. Users will need the VirtualBox program, which requires admin privileges for installation.
