Thanks Anderson,
After I sent the email I tried using -cifti-separate to get metric files. With them as input, PALM worked as expected.

Hi Sally,
Indeed, this is a simple case -- a one-sample t-test -- and it should go smoothly. 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.
All the best,
Anderson

Hello Anderson,
Thank you for all the work you’ve done on PALM. 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).
Running PALM alpha102 using MATLAB 8.3.0.532 (R2014a) with the following options:
-i data.32k_fs_LR.dscalar.nii
-accel tail
-n 200
-nouncorrected
Found FSL in /usr/share/fsl/5.0 #(note - this is version 5.0.8)
Found HCP Workbench executable in /usr/share/workbench/bin_linux64/wb_command #(this is version 1.2.3)
