I am aware of that, but that is not what we (I) want. I don't think we can do
much userul with these files, because they are already processed.

If I understand that correctly, PocketTopo is still completely closed and the
file format not documented. Also from reading your comments, the PDA software
seems to be quite inflexible (first splay shots, then next target). Since I am
also considering going that route, these seem to be severe limitations.

Working together with people using PocketTopo, it is quite inconvenint not to
have true Therion *.th files with the full set of measurements, but just
processed data. It would be great to be able to write a *.top conversion
utility, but for that the file format needs to known.

Best, Martin
