 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 1G.
 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.
