BEFORE I REINVENT THE WHEEL...

Has someone created and posted a study template that we can copy/paste from?

Thought I would ask first BEFORE I create one from scratch.

Since most of the code is that same, I find it much easier to copy/paste when I create a new study.

THANKING YOU IN ADVANCE.


Here's an example of what I mean:
