You can create a measurment file, say, MEA.MDT containing: DIST 1 5 DIST 1 6 DIST 3 7 ...
Import the TPS file with scaling into Morpheus, append the above file, then export the data to a matrix format. The distances will be labeled columns of that file. Note that distances are invariant to translation and rotation, but not scaling. I.e., you probably don't want to do any superimposition. -dslice On Fri, 2005-06-10 at 10:57, morphmet wrote: > I want to perform comparative anlyses of shape variation using trusses > and newer geometric analyses (including outlines).
