SAMPLE VIEWER "Execute failed: java.io.IOException..."

Hello everyone,

when I try to upload the metadata input file, I get a series of errors and no mapping file is added to my MEGAN session.
I always use QIIME and my metadata input is the same mapping file (.txt) I use for the analysis, so it works and follows the parameters, such as tabs-separated fields, first line as #SampleID, BarcodeSequence ecc. Never had problems in QIIME (v 1.8.0). The data I use is the biom file generated with QIIME.

When it comes to MEGAN (v 6.8.13), I get these:

What can I do? What’s the problem?
Thanks in advance.

The problem is that you need to use the Oracle Java Runtime Environment, not OpenJDK.
This is described in other posts in this forum (search for linux)
