Sometimes you need to rename a series. Maybe it was collected in error or was a bad series; you want to keep it, but rename it so the series isn't automatically picked up in pipeline processes or searches.
On the study page, find the series, or series(s), you want to rename. On the rightmost column, check the checkbox(es) for the series. Scroll down to the With Selected... menu.
From the menu, select Rename
Rename the series(s) and click Rename.
The series(s) will now be renamed.
Click the protocol name for the series, and an edit box will appear. Edit the protocol (series name) and press enter.
