SDM preparation

Preparing the folder

SDM software assumes that all files needed for a meta-analysis are in the same folder.

Files to put in the folder

The peak coordinates of each study must be written in text files, whose name must be the name of the study plus one of the following extensions:

- .mni.txt if coordinates are in MNI space (e.g. Smith2004.mni.txt).

- .mni2tal if coordinates were converted from MNI space to Talairach space using the Brett's conversion (e.g. Smith2004.mni2tal.txt).

- .tal.txt if coordinates are in correct Talairach space (e.g. Smith2004.tal.txt).

Each coordinate must be written in a line using the following pattern: x,y,z,sign where sign is either p (positive difference) or n (negative difference), e.g.:

-8,46,3,p

12,2,2,n

18,22,4,n
