I can’t quite work out why you get that first error message. The command line looks. What I would suggest is you rename your image files to something without an underscore, though I must admit it seems a little unlikely that is the problem.
Your next error message on the other hand means that you have no image file with the basename JTDTI_down in your current directory.
