Dear All I am interested in using EFA3D to calculate Fourier coefficients for some curve data taken on human crania. However, this program only has limited supplementary information as yet so I have a few questions:
1) Do all homologous curves first need to be placed in the same frame of reference given three common landmarks before co-efficients can be computed? 2) Can I then place all homologous curves in the same input file even if they each have varying number of points making them up? 3) If anyone has used this program before perhaps you can spell out what the first line of the input file refers to: i.e. 1 1 180 0 DIM=3(that's presumably dimensions?) Perhaps some people have used alternative programs for such analysis? I am aware of several 2D versions but no other 3D ones. Any comments, suggestions and advise are gratefully accepted!
