I am trying to read in 2D slices or raw data using MetaIO and view it using the fltkImageViewer. Can I specify a file prefix for each slice in the header? All I've seen so far is if all of the raw data in one file. Thanks. -darby j --------------------------- Darby J Brown SCI Institute University of Utah Email: darbyb@cs.utah.edu Phone: 801.587.7878 ---------------------------
