However it looks very tiny and somehow hard to see. Is there a simple way to make it look thicker. I wanted to do it using Mark("positions")-->Connect--->Tube. But it didn't work.   Many thinks in advance, MSB

But the problem was the way I was importing my input data. Actually I usually need to clip parts of the volume so that the data confined within a predefined box is only shown. A simple way to do this kind of clipping has been described at:     http://www.opendx.org/cgi-bin/forum/YaBB.pl?num=1179477724/3#3     By doing so, surprisingly, i can't pass my isoline  to Tube, but as soon as I import the whole data file, everything works just fine!

Tube (and other modules) cannot deal with this, so you get the error. For this reason, clipping is usually done later in the process (like - right before Image).   Joel
