To install extension "Sequence registration"

Dear Dr. @lassoan,

I want to use the extension “Sequence registration” to register 4D DSC images.
However, buttons on the panel look different from the manual (https://github.com/moselhy/SlicerSequenceRegistration).

Here’s mine.

Moreover, Input volume sequence seems to be not activated.
My Slicer is Slicer-4.9.0-2018-08-20-linux-amd64 version (latest nightly build),and Stable release (Slicer-4.8.1) shows also the same screen.
How can I fix it?
Thank you in advance!

We continuously improve the module, but we don’t always update illustrative screenshots.

You need to load volume in a Sequence node. You may have loaded your 4D data set as MultiVolume node. To convert a Multivolume node, save it to a file and when you load it again, choose “Volume sequence” in the “Add data” dialog.
