  • Directly opening Jalview with a JVM

    + Launching Jalview directly with a JVM is entirely possible, but is not recommended as automatic updates and some other default settings will not operate.

  • + However by launching Jalview in this way you have full access to the Java command line arguments. + In particular you can set the maximum allowed memory with the -Xmx... JVM argument. +
    + -Xmx should be immediately followed (no space or equals) by the maximum amount of memory that you might want to launch Jalview with. This can be specified in bytes as just a number, + or in kilobytes, megabytes or gigabytes by following the number with a "k", "m" or "g" respectively. e.g. + 

    +      -Xmx8g

  • + Jalview binaries for Windows and macOS are distributed with their own JVM which you will find in +

    + For linux and other unixes you will have to install a Java 1.8 JRE (we recommend the ones found at https://adoptopenjdk.net/)

  • + You will also need to reference the "appdir" release folder with all of the Jalview jar files. +
    + On Windows this will be + 

    \PATH_TO_JALVIEW\release
    + whereas on macOS it will be + 
    /Applications/Jalview.app/Contents/Resources/app/release
    + and on linux or unix + 
    /PATH_TO_JALVIEW/release

    +

    + Assuming the java (or java.exe on Windows) commands are available to you, you can run, e.g. + 

    +      java -Xmx1500m -cp "/PATH_TO_RELEASE_DIR/*" jalview.bin.Jalview
+
    + or on Windows + 
    +      java.exe -Xmx1500m -cp "\PATH_TO_RELEASE_DIR\*" jalview.bin.Jalview
+
    + Note that the classpath argument wildcard must be simply a '*' and not '*.jar'. This is a limitation of Java. +

    +

    + You can also add other Jalview command line arguments as above after the jalview.bin.Jalview class name (you cannot use jvl files if launching Jalview in this way).
