Has anyone had trouble getting HDR edit to work on SPM99? I'm using SPM99 on an NT. The Display function is having no trouble reading the image files. But when I use the HDR edit function to set a parameter like "origin" and then apply it to some image files, nothing happens. The "thermometer" appears momentarily to indicate the status of the conversion job but the image files don't appear to change. Moreover, when I examine the modification dates on the files, I find that SPM didn't actually change the files. I also checked to make sure this isn't a permissions problem. Any suggestions?
