[ome-users] Maximum size supported in OMERO Importer

[Nandakumar, Sriramkumar]

Hi Brian,
Thanks for the reply.
We are trying to upload large image size of around 300 MB in Omero Importer. 
However it is not possible for us to upload JPEG image of 25 MB in Omero. The importer shows the status as "Analyzing".
Since for our research we are dealing with large image sizes of more than 100 MB we are finding very difficult to upload images.
Is there any other image format which is compatible with Omero for better uploading?

Thanks in Advance.

Thanks & Regards,
Sriram.

Hmm.. tricky question.

The importer is set to use up to a gig of available RAM on your machine. What that translates to in terms of 'how big of an image' however is very dependent on what format is being imported.

If your importing a simple format with little metadata, (like a basic tiff image), this should allow you to import images where each plane is about 500 megabytes in size. (there's only a small additional overhead for organizing multiple planes). More metadata rich formats will lower the amount of available memory available for the plane import process, but it shouldn't be too excessive.

Are you asking this question because you have a specific importing problem?
