Hi Jennine,
A single color is all you should get (since your awk command is extracting
only the node indices). If you also want the values that are in your label file,
add $5 to the awk command. By the way, why are you having awk print out
the 1, 0, 0?
Try this:
awk '{print $1, $5}' area.sed > area.1D.dset
That will give you a file with 2 columns, nodes and values.
On the other hand, you should not need awk at all. If you load the 'area.sed'
file into suma directly, you can just view column #4 for intensity (since
columns are 0-based in suma, but 1-based in awk).
