In case anyone's interested, here is some example data:

http://www.fileden.com/files/2008/7/19/2010361/data.txt
They contain the same data  the txt file is just a tabdelimited ascii text dump of the data in the xls file.
First column is time, the next 27 columns are the {x,y,z} sets for 9 marker coordinates.
About 260 rows representing about 1.7 seconds worth of data.
The markers are numbered in correct pathorder from 1 to 9 (and back to 1).
