In order for PMA.core to show content, you need to set up root directories. A root directory is a starting location from which your various whole slide images will be hosted.
The reason for working with root directories offers several advantages:
The concept of root directories is not dissimilar to mapped network drives in the Microsoft Windows operating system, where you map a map such as \\myserver\dir\subdir\subsubdir\ to a (much simpler to remember and address) drive letter.
Since PMA.core 2, a root directory is defined by one or more mounting point. This was done to be able to facilitate geo-replication scenarios.
A mouning point for a root directory may either be a local directory, a UNC share, Azure blob storage, FTP folder, or an Amazon S3 compatible storage.
A Mounting point is a further abstraction of the concept “where are my slides stored?”. While most users will end up having one mounting point per any one root directory, here are the different scenarios in which you could have multiple mounting points:
In order to make root directories work, you need to attach at least one mounting point to it.
The mounting point of a root directory refers to the base directories where the system should look into for whole slide images. All the subdirectories of the root directories are exposed by the application and whole slide images that are discovered are advertised.
The next section takes you through the different steps that you can take to configure root directories and mounting points. We also talk about the security precautions that you can take when configuring these.
This section allows the addition of new directories as well as the editing and deletion of existing ones.
The path of a directory must be an absolute path accessible by the host computer. Should the path not exist, an error message is shown:
You can edit already existing root directories by clicking on the pencil behind each entry in the overview table:
Similarly, you may delete root directories by clicking on the delete icon behind each entry. A confirmation prompt at this point will give you one last chance to reconsider:
