Registration

There are several tools that enable to spatially transform one or several of the shown images. Typically, the reason to do this is to “register” images in a multi-modal imaging setting, thus the tools are called “registration” (and not “transformation”).

Output

While all registration tools work differently and require different inputs, the output are always transformed images. MoBIE will not re-save the image voxel data, but only save the transformation as a new “view” on the voxel data. This new view will be added to the MoBIE UI in a group of your choice, the name of the view will be the name of the input image with a postfix of your choice, e.g. “-transformed”.

In addition, one must choose whether and where this view should be saved. Currently, three options are supported:

• “Current Project”: Traditionally, images in MoBIE are loaded from a JSON based MoBIE project to which new views can be saved. Currently, selecting this option when the data has not been loaded from a MoBIE project will lead to an error message.
• “External File”: In recent years several new ways have been added to load data into MoBIE, which do not follow this project structure. In such cases views can be saved into a stand-alone “external” JSON file that contains the view. Even if you are loading data from a MoBIE project you sometimes may not want to alter the project; also then saving the view to an external file can be a good option.
• “Don’t Save”: This option can be a good choice when you are exploring different registrations, but do not want to store those trials.
