[ome-users] ndpi format for double slides

[MEYENHOFER Felix]

Hello

we recently got a new NanoZoomer that is able to load a new slide format (double-slides). The output format is still the same, but when importing these file in OMERO we experience some problems with the rendering at certain magnifications. Also for the double slides Bio-Formats does not seem able to retrieve the pixel size and other metadata. 

I put a couple of screenshots and an example file on my ftp server:
https://drive.switch.ch/index.php/s/15i2KnMv2TQ3iW5

Furthermore I reported some cases when the OMERO has some serious troubles when accessing some of these files [1]. In these instances the I even loose the connection session and I need to login again. 

I was also talking to the Hamamatsu specialists. There is not much they can do, since they are not involved directly in software development, but apparently Hamamatsu would be willing to provide their API libraries. Now, I do not know if this would help in the context of Bio-Formats, but maybe it just might...

Any help towards resolving this issue would be highly appreciated

Best regards, 

Felix
