General concepts

Here we introduce general concepts about OMERO: project, dataset, image, navigation, renaming, moving images, changing groups, etc.

OMERO has only 3 main entities, they are:

  • project project (grey folder)

  • dataset dataset (green folder)

  • image

A project can contain datasets and images, but it cannot contain another project or sub-project. Similarly, a dataset can only contain images, it cannot contain another dataset or project. There is no nested project or dataset

  • Each user can belong to many groups. At the Crick, each user belongs to

    • default

    • Training

    • Demo

    • Lab-<group>

  • In this workshop, each user also have an additional group

    • Training_Jan_2025

  • When a user login, the system is set to assign and display their Lab-<group>.

  • Lab-<group>’s owner is the PI of the group.

  • Each user can rename and remove (not delete) their own images. * remove means removing it from OMERO system view. The image data still resides within OMERO controlled storage space.

  • Members of the group can read and annotate other members’ images, but they cannot write or rename them.

  • Group default is only accessible by user and are not viewable by others.
