Good afternoon!

         I am working on a fractional anisotropy meta-analysis with more than 10 studies, and I have two questions. Thank you so much for your time and help!!

1. First, an error is coming up when I try to create a mask of the peak coordinate. Am I doing something incorrectly? How should I set things up so that I can create a mask, extract the values, and run the Egger test? 

Here is the execution log message: 

Launching Mask creation...

Launched: sdm -10_20_18 = mask coordinate, -10, 20, 18

Creating mask...
WARNING: The template does not contain the specified coordinate

2. When I run the Funnel plot/Egger's test analysis, the output does not provide a valid p-value. How should I interpret this p-value?

Bias: 0.00, t: -1.#J, df: 65, p: 1.#QO.
