Support

We do our best to test MeV on the most popular hardware and operating systems. Our goal is to support the most recent version of MeV on all major releases of the big three OSes (Windows, Mac OS and Linux) within six months of their becoming available. However, this policy is sometimes not upheld because of the limits of our budget. For instance, we do not currently have a computer with Mac OS Snow Leopard available for testing. In cases such as this, we do our best to troubleshoot problems that our users report to us, but we cannot guarantee anything. If in doubt, check the list of supported platforms There are many places to get support for MeV. Please start with the MeV Quickstart guide. The Frequently Asked Questions page (FAQ) may also be useful. For more detailed information, the MeV Manual is a complete reference for all of MeV's features. Some common tasks are covered in the Tutorials section of this website. If the above resources do not answer your questions, please ask a question on the MeV Sourceforge help forum.

MeV and R

As of v4.5, MeV for Mac OS requires R v2.9, and will not function properly if another version is installed. This means that any MeV for Mac users that have installed R v2.10 will find that MEV is unable to run the LIMMA module, as it depends on R. When version 2.10.1 of R is released (currently scheduled for Decepber 14th by the R project) we will be assembling a version of MeV that will work with R v2.10. We will also be providing an upgrade script that will allow previous installations of MeV to work with R v2.10.x.

Supported Platforms

MeV is written in Java and expects to run on Java v1.6 or higher (v1.5 for Mac OS). Therefore MeV should run on any system that supports the appropriate Java version. However, no system is perfect and occasional platform-specific glitches do arise. We attempt to test MeV on the most common platforms. The current well-tested platforms (for MeV v4.4) are listed below. Windows XP / Java v1.6 Windows Vista / Java v1.6 Windows 2000 / Java v1.6 Mac OS Leopard / Java v1.5 Red Hat Linux / Java v1.6

Running MeV v4.5 on a 64-bit computer

Version 4.5 of MeV uses a library called JRI to connect to the R statistical environment, packaged with MeV. A difficulty of the JRI library with 64-bit Java means that some parts of MeV will not function when run on a 64-bit Windows computer running 64-bit Java. This difficulty can be overcome simply by installing the 32-bit version of Java and ensuring that MeV uses it. Instructions for Windows users are below.

 

Instructions for using 32-Bit JREs on 64-Bit Windows

Step 1:

Install the 32 bit Jre6 from one of the locations below: Please accept the install location as :

"C:\Program Files (x86)\Java"

From Sun:

MeV local copy:

Step 2:

Browse over to the MeV_4_5_0 folder.

Open the TMEV.bat file in text editor.

Add the following lines *after the line that reads :CMD

REM Set JAVA_HOME **Only 32 Bit JVM is not default

REM Assumes you have already installed 32 Bit JRE

REM following instructions at MeV SourceForge forum

REM This not required on a 32 Bit Windows machine and

REM only required if your 64 Bit Windows machine does REM have a default 32 bit JVM

REM NOTE: This does not alter any of your system settings REM All changes are local to this file/environemnt

set JAVA_HOME="C:\Program Files (x86)\Java\jre6"

set PATH=%JAVA_HOME%;%JAVA_HOME%\bin;%PATH%

Save TMEV.bat

Step 2: (Alternative)

If you have followed Step 1 correctly you can just copy a new launch file called TMEV_64.bat from here.

Put it under the folder MeV_4_5_0.

Use TMEV_64.bat to launch MeV
