    I am trying to use the ImageMath subfunction TimeSeriesSubset to crop my BOLD images.
    When I run what seems to me to be the correct syntax,
    >ImageMath 4 new TimeSeriesSubset Test_BOLD.nii.gz 100
    I get the following error:
    libc++abi.dylib: terminating with uncaught exception of type std::out_of_range: basic_string Abort trap: 6
    I've also tried
    ImageMath -d 4 new TimeSeriesSubset Test_BOLD.nii.gz 100
    and got this error:
    Dimension 0 is not supported
    And I tried it with no # of images
    ImageMath 4 new TimeSeriesSubset Test_BOLD.nii.gz
    and got
    Segmentation fault: 11

    What am I doing wrong?
    Also, when I choose a # of images, are they taken from the start, end, or middle? I am trying to remove the first 10 timepoints before I process the fMRI data, and I assume that this is the correct function to do so.

      recommend ANTsR for something like that ...
