[ome-users] slow or failing import of large files with large X by Y size

[Damir Sudar]

Hi all,

On my installation (Omero 4.4.5/Ice 3.4 on Ubuntu 12.04LTS 64-bit) I see 
the following strange import (using Insight/Importer 4.4.5) behavior:
File1.lsm: 102MB is 5120 by 5120 pixels in 2 channels takes 30-40 
minutes to import
File2.lsm: 207MB  is 1024 by 1024 pixels by 50 Z-slices takes 1 minute 
to import
File3.tif: 100MB  is 10240 by 10240 pixels simple 8-bit TIFF, import 
finishes in a few seconds without errors but the resulting image in 
Omero will not open and gives error: "The image could not be opened. The 
image is not a valid image." But the archived version can be downloaded 
without trouble.

So there appears to be something wrong with importing image with large X 
by Y sizes. Has anyone seen this as well and is there a solution?

Thanks,
- Damir
