I've found that calculating linear distance measures is quite easily done in a spreadsheet or database program. For two-dimensional data, as long as you have the XY coordinates for each landmark, you can calculate the distance between them using good ol' pythagorean theorem. In this case, A-B distance = √[(XA-XB)^2+(YA-YB)^2]. Actually, I find calculating distances this way is usually quicker than doing so in some of the imaging/digitizing software, especially if you have larger sample sizes.
