Hi Lydia,

Many thanks. 

I am using AES SDM v 5.15 as I have combined t-maps in my analysis. When I type the command you mentioned, or replace 'MyTest' with 'MyMean', SDM aborts.

When I use the latest version of SDM, in the execution log it reads 
"wParser error: argument 'model name' missing."

If it is useful, the coordinates I am using are (x y z MNI)
(36 -76 -48)
(-12 -74 -44) 

Best wishes,
Brandon
