OMERO development of JPG XR compatibility in Bioformats and for server.


Between 2013 to 2016 following presentations, collection visits, and research the consortium was established.

Summary - DEC Beginnings 
Slide Scanner

A key to the project was to evaluate the slide scanning options.

  • Many of the collections have historic (irreplaceable) slides and most modern slide scanners are primarily designed for pathology labs where the slide preservation is not crucial.
  • Many of the collections have slides of non-standard historic dimensions.
  • The scanner requires easy transport and set up at each new location.

The Zeiss axioscan met all the above criteria.

  • Slides are never mechanically handled once loaded onto a carrier rack.
  • Slide racks can be manufactured to deal with non-standard slide sizes.
  • A scanner carrier case is available for ease of transport.
Online Database Software

A well supported and freely available software was required for this large image database.

  • Zeiss provides Zen software, that is licensed and requires ongoing subscription as well as expensive for storage space.
  • Glencoe provides OMERO software that is widely used internationally by research institutes, labs and journals (J Cell Biology).

Current DEC Collections

  • OMERO updated to version 5.3 now JPG XR compatible.
  • Server - Quad-Core Intel Xeon E5 Processor Speed - 3.7 GHz
  • Storage - 2 x Areca ARC-5028T2, Thunderbolt 2, 6-Bay RAID 5 - 72 TB


2017 completed first collection scanning and testing of the updated online database software.

Summary - DEC Current 
Scanned Slide Files
  • The original - The HDD containing the scanned slides files are held as an archive by the original collection curator.
  • The DEC copy - The files are then converted from CZI format ( 1-4 GB each) to a compressed JPGXR format (200-400 MB each) onto a separate DEC HDD.
    • These second HDDs are stored in Australia.
  • The online version - The compressed images are then batch uploaded onto the DEC server.
    • DEC server database is protected in a RAID 5 storage system.

This means there are always at least 3 separate copies of the original data in 3 different locations.

Online Database
  • 2016 - Server was run continuously with sample uncompressed images to test stability.
  • Mar 2017 - software updated to import the JPGXR format files.
  • Server is currently being tested for remote uploading of files from international locations.

4. DEC Online

Below is a link to the Online Image database - a single section on a slide from the Blechschmidt collection.

Online Image Database - Access  
Please note that only registered users who have agreed to the DEC usage conditions can access the database images.
