Hi,

We have an electron microscopy facility in our institute and when i tried to visualize one of their image (.mrc) in the insight viewer i encountered some issues:

The rendering settings are bad, i cannot really see the objects i m supposed to see on the image because it s too grey...i see them when i open it on imageJ that displays the image as i see it during the acquisition. I wanted to enhance the contrast on omero.insight using the rendering effect tools but when i click on the icon to access it, i can't see the rendering options in the right pannel but i see a black screen instead...Otherwise no problem to open the file in itself.
I should precise that we're using omero 5.0.5, maybe this bug is fixed in 5.0.6...?

I have another question that is not related: does the volume viewer (astex viewer?) works on omero 5.0.5?
and is there any omero script/plugin to create a 3D view from a stack of images?

Best,

Alex.

Hi Alex
i reckon your em files have floating point values. We have added support for 32-bit and floating point in 5.1
and are planning to back port some of those changes to the 5.0.x line
It is not in 5.0.6
Could you submit one of the faulty files to be sure it is correctly supported?

Regarding the openAstex viewer, it is currently not working against 5.0.x. The Volume viewer button in the Web should be disabled.
We currently do not have a script to generate a 3D view from a stack of images, something certainly useful to add to the list.

Regards
Jmarie

Hi Jmarie,

Thx for your answers.
I don't mind submitting the image if you explain me how to do it ;) .
It's a 3 or 5 gb file if i remember well, is that a problem?

Regards,

Alex.
