Data should be uploaded either as a tpsDig (.tps) or .dat file. tpsDig files (which are easy to collect using Jim Rohlf's tpsDig and tpsUtil) are are of the format:
IMAGE=176 Acer neg01.tif
If the first line of your dataset starts with "LM=", it is read as a tpsDig file. Specimen names are read off the IMAGE line (generated automatically by tpsUtil). Your specimen names can't contain "LM=", "IMAGE=", or "SCALE=".
Alternatively, .dat files are of the format:
OBJECT Vulpes 001
OBJECT Vulpes 002
The delimiter "OBJECT" is key (case is ignored). Specimen names are taken from the line with "Object". Your specimen names cannot contain "landmarks", "LM=", "scale" or "object". The section with landmarks comes at the end of each object (you may alternatively use the tpsDig style "LM="). Standard eigenshape doesn't use the landmarks, but it is okay with them being present in the file (they are ignored).
Either format can have a line with SCALE or SCALE=, if you wish to include a scale factor. The data files may have empty lines, but may not have a title line. There may be problems with Mac text format files. If you discover the best way prepare these files, let me know. I find that, on a PC, saving as text from Microsoft Word generates good text files. I edit the text files in Notepad.
