This is a very convenient tool to overlay one window onto another with transparency.
This is useful for people needing to do manual brain slice to atlas registration.
== Dowload ==
It is free, but only for windows at https://github.com/paulodeleo/OnTopReplica/releases
== Use ==
After installation, running the software creates a window. Right click into it to select **which other open window you want to have on top **.
Then by right clicking you can select the **Opacity** and the **Click trough** behaviour.
=== Opacity ===
Select {nav Right click > Opacity > % Opacity}
{F5906027, size = full}
=== Click Through Behavior ===
Select {nav Right Click > Advanced > Enable Click-Through}
{F5906045, size=full}
To disable **Double click** on the OnTopReplica icon on the Windows Taskbar
You can get the opposite behavior by selecting {nav Enable Click Forwarding}
This means that if you click in the OnTopReplica Window, it is like clicking inside the original window.
