+Trinity memory usage
+====================
+
+As described on the official Trinity website
+`FAQ <http://trinityrnaseq.sourceforge.net/trinity_faq.html#ques_comp_resources_required>`_,
+trinity requires a large amount of memory to perform the assembly: "roughly
+~1G of RAM per 1M reads to be assembled"
+
+By default, this tool is configured to limit the memory consumption to 30G.
+You might need to lower this limit if the machine(s) executing the jobs have less memory available.
+If you have a lot of reads to assemble and a machine with enough memory, you can increase it.
+In both cases, you can edit the TRINITY_MEM_OPTIONS in the file:
+
+<tool_dependency_dir>/environment_settings/TRINITY_MEM_OPTIONS/iuc/trinity/<hash_string>/env.sh
+
+to lower the maximum memory usage to 2G for example:
+
+TRINITY_MEM_OPTIONS='--max_memory 2G --bflyHeapSpaceMax 2G'
