TPS View is a free, open-source app for building geometric morphometrics datasets. Open your images, place landmarks, set the scale, and save a clean .tps file ready for analysis, on Mac, Windows or Linux.
Everything you need to digitize hundreds of specimens, in one place.
Click to place, drag to adjust, and mark landmarks as missing. Undo works without limit, and a magnifier helps you place points precisely.
Click both ends of a ruler to set SCALE. Every specimen's scale is listed in one table, where you can edit values or apply them in bulk.
Pick which image belongs to each specimen. Windows paths like C:\…\img.jpg are found automatically, and missing images can be relinked from a folder.
Start a new TPS file from a folder of photos, or drop more images onto the window to add specimens.
Flags inconsistent landmark counts, missing scales or images, and duplicate IDs before you run your analysis.
Export coordinates in pixels or real units (scaled by SCALE), ready for R, Python or Excel.
TPS View reads and writes the standard TPS format: whole-pixel coordinates measured from the bottom-left corner, and SCALE in units per pixel. Your existing files open as they are, and the files you save work in the tools you already use for analysis:
TPS View is free, so it isn't signed with a paid Apple certificate. macOS asks you to approve it once.
.dmg, open it and drag TPS View to Applications.If macOS says the app “is damaged”, run this once in Terminal:
xattr -cr "/Applications/TPS View.app"
