Hi Prof. Smith,
Thank you so much. There are some overlapping voxels between the two, but the macbook pro generated a much larger number of voxels than Ubuntu before thresholding. Also, a small set of voxels were significant (p < 0.05) from Ubuntu, whereas no voxels were significant from macbook pro.
In Ubuntu, 'fsl version 4.1.9-4ubuntu1' was installed and 'fsl4.1-randomise' was used; whereas 'randomise' was used on macbook pro. I thought they were equivalent. Could you please let me know what I might be missing? Thank you so much.
Best,
Tiffany

Hi - *how* different are they (before thresholding of course)? Don't forget the clue may be in the name of the program…..

For the same study setup with the exact the same design (.mat, .con) files, however, the results I got are different on the two platforms. I was wondering what caused this discrepancy? Thanks so much.
