FAQs

Browsers

1. Can I use my favourite browser ?

Yes, as long as your favourite browser is one of the following:

• Mozilla 1.6 and higher
• Netscape 7 and higher
• Firefox
• Galeon
• Konqueror

All of these are available free of charge for many operating systems. We recommend to use the Firefox browser.

1. Why can't I use my favourite web-browser XYZ (eg. IE from M$)?

We currently do not support all existing browsers. EMMA does not function with or looks ugly with at least:

• Netscape 4 and less
• MS IE
• lynx ;)

Trying to support more different browsers while providing a high level of interactivity requires much more effort for testing and web/javascript development. Although there are some 'standards' each vendor has its slightly different interpretation of what this 'standard' means. We decided to spare us some time which can be better invested into new features and interactivity instead of supporting any of those 'standard' browsers.

If you want to use EMMA 2 please feel free to download and install one of the suported browsers.

Web Interface

1. I added Arrays to my experiment, how can I add more, the link is gone?

For a completely empty experiment, EMMA will show the following links in the experiment overview:

---

No arrays used in this experiment.

You can import from ArrayLims or select Arrays existing in the current project.

---

After importing your first arrays, you will see this link instead:

---

Link arrays

---

Of course, you may still import as many arrays as you wish. On the left you will find the following link under Basic Actions:

Jobs and Pipelines

1. I have submitted an analysis job, do I have to stay and wait for it? [BR] No, you don't. In fact, the job will run fine without any further intervention from your side. You can continue with other work in EMMA, submit more jobs or log off the computer. If you come back later, you will find all jobs in your experiment. The results are listed under View Results in the Basic Actions menue of your Experiment.
2. My job has failed, what can I do? [BR] First: please read the message, the job has given. Often, the message explains the reasons for a failed job. If it looks somewhat cryptic to you, it could well be a software error. In this case, and only in this case, don't delete the job and give feedback. Send an email to >:> emma-devel >:> mailing list, giving the following information:
3. the EMMA project you are using
4. the experiment you run the job on
5. copy/paste the data from the view-results page for that job
6. My job stays in the submitted state for hours! [BR] Sometimes, this can be due to a high load on the compute cluster. If you encouter this situation, don't resubmit the job and don't delete the job. It's likely that a newly submitted job will not work, either. Instead, proceed as above.
