Hi Michael and Anderson, Of course, the problem turned out to be at my end, I think. The reason I needed to separate the CIFTI files was to convert rows to columns. Since I didn’t put a design matrix in the simple command, I didn’t get an error. When I tried to reproduce my problem, but using the design matrix, I got an error. But PALM read the CIFTI files in just fine. Still learning about CIFTI files. Sorry for the false alarm, Sally On Dec 15, 2016, at 5:01 AM, Anderson M.

So, if you could help us by providing your actual command input to PALM, and testing those options that Anderson suggested, that would be appreciated. cheers, -MH -- Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave.Tel: 314-747-6173<tel:314-747-6173> St. Louis, MO 63110Email: [log in to unmask]<mailto:[log in to unmask]> On 12/14/16, 6:09 AM, "FSL - FMRIB's Software Library on behalf of Durgerian, Sally" <[log in to unmask]<mailto:[log in to unmask]> on behalf of [log in to unmask]<mailto:[log in to unmask]>> wrote: Thanks Anderson, After I sent the email I tried using -cifti-separate to get metric files.

The step where you say it hangs (when it generates the 200 sign-flips) isn't one what would cause difficulties. Nonetheless, could you try again adding the options "-cmcx" and "-cmcp"? Thanks.

I had it working for some nifti data files, but when I tried a really simple case with CIFTI files, matlab seemed to hang up before completing any of the randomizations/sign changes. It doesn’t seem like such a difficult design that it would take a long time. Do you have any idea what the problem might be? Your help is much appreciated, Sally Here is what I see in the matlab window (and then I can wait for hours and not see anything more).
