Beast2 install in Linux

[Franz St John]

I was successfully tinkering with BEASTv1.8.1 when I realized that I should probably be using BEAST2. All associated programs were working (e g, beast, beauti, logcombiner, treeannotator...and so on). I downloaded BEAST2 for linux and unzipped in my programs folder.  Replaced the path to BEAST1.8.1 with the path to BEAST/bin in my bashrc file.  Restarted for good luck.

I get the below message from any of the command line scripts such as beast or beauti except densitree, which appears to opens fine.  Making the individual .jar files in BEAST/lib executable would not open them in Java 7 or 6 except for DensiTree which opened in Java 6. I'm sure I've done something silly, any guidance would be appreciated.

Hi Franz,

Most applications in the BEAST v2.2 package require Java 8.

Cheers, Remco
