Hi Alfonso,

The output when I run this in MATLAB reads as follows:

------------------------------

800x1 struct array with fields:

fname
dim
dt
pinfo
mat
n
descrip
private
fname: [1x125 char]
dim: [128 120 36 800]
dtype: 'INT16-LE'
offset: 1504
scl_slope: 1
scl_inter: 0
3

------------------------------

Does this give you any insight into what the problem might be?

Thanks again for your help with this!

Jeremy
