The MELD Project is an international collaboration aiming to create open-access, robust and generalisable tools for FCD detection. To this end, we will train a neural network classifier on MRI features from FCD patients from multiple centres worldwide.Protocol 3 provides instructions on how to quality control the FreeSurfer reconstructions.These instructions are based on the freely available protocols on the ENIGMA-epilepsy website http://enigma.ini.usc.eduWe are very grateful to Derrek Hibar, Neda Jahanshad, Roberto Toro, Jerod Rasmussen, Theo van Erp, Esther Walton and Stefan Ehrlich who wrote the orginal ENIGMA protocols and offered them with an unlimited license without warranty! The main change is correct co-registration of FLAIR to T1 is now checked.
