Mixing Commands and Variables

  1. Finding the voxel size
    Create a new script that stores the values of pixdim1, pixdim2 and pixdim3 (the voxel sizes in mm) each in a separate variable for an image, where the name is specified as the first argument.
    Hint: see fslval usage in previous slide

  2. Displaying voxel size
    Echo the value of these variables in a line of the form:
    1.0 * 2.0 * 1.0
    where the numbers are the stored values.
    Hint: remember to use a backslash before the *

  3. Test the script and keep it for later modification.

    Look here for the cheat.
