You're right. I should have checked into this more carefully before my 
initial reply; I mis-read "piece" as "part". The Extract Parts filter 
requires that the reader / source / filter it's getting its input from 
produces multiple outputs, and the reader of your file produces a single 
output. It looks like splitting the data into separate files is probably 
the best way to go.
