Emperor QIIME2.2018

No. This is what I got:

Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.

For more help, please click this link.

Check out some of the following links to learn more about WebGL and to find more web applications using WebGL.

Sounds like it might be your browser then. Can you try typing “chrome://flags/” into the address bar, then search for “Disable WebGL”. Disable this option if you haven’t already. If you follow these steps and still don’t see an image, go to “chrome://flags/” and then search for “Override software rendering list” and enable this option.

Hi Yoshiki,

WebGL was already Disabled. I enabled Override software rendering list and still don’t see the image. As a side note, I can see the cube using Internet Explorer. What do you recommend to do?

Thank you!

Hi @idapantoja,

If those workarounds didn’t work for your computer using Google Chrome, then I don’t think I have a good way to get this working for you. Perhaps one alternative would be to reach out to your system administrators and ask them for an updated version of Google Chrome or Firefox.

Lastly, although I haven’t done any testing using Internet Explorer, it would be worth a shot to try to open view.qiime2.org there.

Hi Yoshiki,

Thanks for your help. I will request an update for this browsers.

I tried to open http://view.qiime2.org/ on Internet Explorer and it says Incompatible Browser.

Thanks again!

Hi Yoshiki,

We have the last version of Google Chrome installed in our computers. Do you think we are missing any of the privacy settings related to Emperor?

Thanks!

Hi @idapantoja,

I don’t believe there are any privacy settings that need to be modified in order for Emperor to work. Are you seeing a different error in the newest version of Chrome, or still the same error as before? If you have the latest version of Google Chrome, are you able to see the rotating cube here: https://get.webgl.org ?

Hi @yoshiki,

Same error. I am not able to see the rotating cube.

Thanks!

@idapantoja, that is very puzzling. Unless we are overlooking something, I think the problem might be that your graphics card does not support WebGL (the underlying technology powering Emperor). If this is the case then I don’t really have a workaround.

@yoshiki, thanks for all your help! One last question: is there a way for you to enable Mozilla Firefox ESR for Qiime2 View? The IT guy here has a feeling that if you enable that then Firefox will work as well.

He said that Chrome is probably going to be a no go now as he found out it is a security setting and deals with WebGL.
Thanks a lot for your help and patience!

Unfortunately it is complicated — that version of Firefox (ESR 52) is missing the main functionality necessary for QIIME 2 View to work (namely, Service Workers). It does look like the latest ESR (60) does have service workers (I think).

Long story short — QIIME 2 View knows how to ask a browser if the browser supports all the things it needs — if QIIME 2 View complains that the browser is incompatible, then it really is in fact incompatible (this is opposed to something like a browser blacklist or whitelist — we don’t do that).

Hi @thermokarst!

Thanks so much for the response. Maybe, this will not be an option but Emperor as a program can be used for Qiime2? I mean, any way to download Emperor instead of using QIIME2 View?

Thanks and best regards,

You can run qiime tools view to load any QIIME 2 visualization locally on your computer.

Hi @thermokarst,

QIIME2 is installed on a Linux server so we are unable to utilize the command you suggested to load the QIIME2 visualization locally. Is the program Emperor not able to be utilized with QIIME2 for the output of the QZV file? Is the program Emperor only compatible with QIIME?

Do you know if Firefox ESR version 68 would be compatible with the Qiime2 View website? We are on Firefox ESR version 60.4 which has service workers disabled. 3D API for Chrome is disabled due to security setting protocols. Trying to find a way to view the visualization data.

Thanks and best regards,
Ida Pantoja

Why not just view the results on another computer? I know that is less than ideal, but, it doesn’t sound like you really have any other options.

Hi @thermokarst,

The work environment that I am in doesn’t allow the use of another computer that isn’t a Windows OS. We are unable to utilize personal machines due to security control measures. This applies to use at home as well.

Thanks and best regards,

I do not know offhand. The easiest way to figure it out is to install and check to see if QIIME 2 View doesn’t complain.

Emperor is a stand-alone program, you can always run it on its own.

Can your IT team install the QIIME 2 VirtualBox image?
