| − | Let's connect to UF VPN (https://kb.helpdesk.ufl.edu/FAQs/VPNInstructions) and then use the xpra script from https://wiki.rc.ufl.edu/doc/Xpra#Microsoft_Windows in a MobaXTerm terminal on a windows client machine (for example). If you run
| |
| − | | |
| − | sh xpra attach ssh:jdoe@aaa-bbb.rc.ufl.edu:7176
| |
| − | | |
| − | in MobaXTerm you should see a password window from TortoisePlink. After you enter the password you should see the mzMine GUI show up on your local machine. Do not close the program with the [x] close button in the right-top corner of mzMine GUI window unless you want the job to complete. Click on the MobaXTerm terminal where you started the command and use 'Ctrl+c" key combination to detach from the session, so you could re-attach later.

Description
mzmine website
MZmine 2 is an open-source framework for processing, visualization and analysis of mass spectrometry based molecular profile data. It is based on the original MZmine toolbox described in 2006 Bioinformatics publication.
Environment Modules
Run module spider mzmine to find out what environment modules are available for this application.
System Variables
- HPC_MZMINE_DIR - installation directory
Additional Information
mzMine can be run in a batch mode according to mzMine Manual by calling startMZmine with a single argument corresponding to a saved batch script generated within the GUI.
We provide an alternate startMZmine script that correctly sets the HEAP memory based on either the HPC_MZMINE_MEM environment variable or, if that variable if absent, based on the total amount of requested memory within a job. Pleas see the sample script below. Note that it appears to be necessary to simulate a virtual X11 environment for mzMine to run in batch mode.
Note that HiPerGator2 nodes are diskless, so '/tmp' directory that mzMine uses by default for its temporary files cannot be used. See Temporary Directories for details on how to set $TMPDIR variable that points to a directory in your /blue space.
If you need to run mzMine GUI, you should use OOD and the HiPerGator Desktop application.
