Hi,
Regarding the opening of RGB images on ImageJ:
The “Color mode" needs to be set to “Composite” in the “Bio-Formats Import options” window, while opening the image.
Please let us know if this does not solve your issue.
Regarding the image: ID182043
Although there was a performance issue, we were still able to generate the pyramids on our test-server.
And I was able to view the image with both the clients (web and insight).
The performance issue can be attributed to the way, Bio-Formats scans and reads the tiles from the file.
I have created a ticket on this regard,
https://trac.openmicroscopy.org/ome/ticket/13004
and have added you to the cc list.
Notifications will be sent to your email id, when there is a status change on the ticket.
Best,
Balaji
