Error: differential expression -- Issues with older Trinity tools and tutorials

Hello @YKV

Please review this server’s learning resources and contact information in this prior post:

The information posted is not enough to diagnose the problem. Try reviewing the Job details (“i” icon) report, including the stderr and stdout reports linked from it. Often these tools will report what is going wrong in those reports, but near the end. Right now all that is visible is the very top of the stderr report, and it almost looks as if the environment used to execute the tool failed to build – but that is just a guess. IF that is the actual problem, someone who has administrative access to the server would need to help with that.

The server you are working on hosts custom versions of these tools. There may be a known issue server-side, or they may be able to help in other ways.
