MEGAN on Biowulf & Helix

MEGAN is a MEtaGenome ANalyzer. It can read Blast output. Normally this program would be run on your own desktop, but MEGAN is a memory hog, and some desktop systems may not have enough memory to handle a large dataset.

MEGAN was developed by D. H. Huson et al at U. Tübingen. MEGAN website

MEGAN is a graphical (GUI) program. You will need an Xwindows connection to Biowulf, then you can allocate an interactive session and run MEGAN there.

Interactive session On Biowulf

Allocate an interactive node and run MEGAN there. Sample session requesting an allocation of 10 GB of RAM:

[user@biowulf ~]$ sinteractive --mem=10g
salloc.exe: Granted job allocation 143361

[user@cn0124 ~]$ module load MEGAN

[user@cn0124 ~]$ MEGAN

[user@cn0124 ~]$ exit exit srun: error: cn0124: task 0: Exited with exit code 130 salloc.exe: Relinquishing job allocation 143361 [user@biowulf ~]$
