Hi Hamid, We have been measuring digitisation error and orientation error for our studies for some time now. Recently, I wrote it down in a protocol, which may be handy to you. It has been very useful to us, as it expresses digitisation error and orientation error as a percentage of the shape variation in a sample of your dataset.
Protocol in .pdf format can be found in the 'MISCELLANEOUS ONLINE DOCUMENTS' section (bottom of the page) in the 'Library' at www.morphometrics.org (with thanks to Dennis Slice for posting it). Cheers and any feedback on its usefulness is welcome Dominique Adriaens Prof. Dr. Dominique Adriaens Ghent University Evolutionary Morphology of Vertebrates & Zoology Museum K.L.

How can I calculate the error in landmarking and how can I identify unsuitable landmarks.
