Hi, The script "epidewarp.fsl" included in the FreeSurfer package for field map correction only works for fsl 3.X and 4.X. I searched the mail archive and find the link ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/epidewarp.fsl This new script is supposed to work for fsl 5.X, but I cannot download it. Is the link still valid? Please check or send me a new link to download the file. Thank you very much. XJ Kang
