SDM exploration of the results
Creation of a mask
Masks are used in SDM to posteriorly extract the values in a coordinate or region from all studies and analyses. Masks are saved in separate mask_*.nii.gz files in the corresponding model folder (e.g., analysis_model_name). These files can be used in more than one meta-analysis.
To create a mask
Press the button [Create mask]
Select [Create a mask] in the Tools menu, to open the following dialog:
Command-line and batch usage
m25_0_m20 = mask MyMean,coordinate,-25,0,-20
left_amygdala = mask MyMean,label,41
