+MELD graph requires a 3D T1 (WITHOUT gadolinium agent) and it is optional but advised to include the 3D FLAIR. 
+MELD Graph has been trained on scans acquired 1.5T and 3T. 
+
+It has not been evaluated on: 
+- other MRI scans contrast than T1 and FLAIR
+- MRI scans with gadolinium 
+- 2D MRI scans
+- scans acquired <1.5T and >3T

+It is not appropriate to use this algorithm on patients with:
+- tuberous sclerosis
+- suspected hippocampal sclerosis
+- hypothalamic hamartoma
+- periventricular nodular heterotopia
+- other focal epilepsy pathologies
+- previous resection cavities

 ## **Prepare the MRI data (Mandatory)**
 
 In the 'input' folder where your meld data has/is going to be stored, create a folder for each patient with the ID of the subject.
