While it was not designed for that specific purpose and thus perhaps not
an ideal solution, I think it would be easier to use tpsDig than to have
to digitize landmarks using tpsDig, then use PAST to compute all
distances, and then select just the ones you want. TpsDig has a
measurement mode that will store the measurements as variables in
addition to any landmarks or outlines that were recorded for a specimen.
You can then use tpsUtil ("Build variable matrix" option) to extract the
measurements and store them as a matrix in an NTS file.
