**Convert landmark templates from Webmorph to .tps format for shape analyses**
Note: only works on macOS; assumes faces were delineated with default FRL template (189 points)
**Steps**
- Create an empty temporary directory
- Copy `_TEM_to_TPS.command` file into that directory
- **COPY** your `.tem` files into that same directory
- Double-click `TEM_to_TPS.command`
- A `_DATA.tps` file will be created
The template files used to generate the .tps file will be overwritten/deleted during this process, so make sure not to use your only copies!
NOTE: if the file won't execute, you might have to open Terminal (under Applications > Utilities) and run the following command:
`chmod u+x /path/to/_TEM_to_TPS.command`
**How does it work?**
This is a simple executable text file that can be edited/opened with any text editor.
It works by removing unwanted landmarks as well as curve information, flipping the coordinates upside-down and compiling the individual files into one .tps file.
**Adapting the script to your needs**
- Set the correct image height
For the coordinate flipping to work correctly, the correct image height needs to be specified on line 8 of the script. If your images are, e.g., 1000 px tall, you have to change the following bit of code on line 8 from
`'{print $1, 2848-$2}'`
to
`'{print $1, 1000-$2}'`
- Decide which landmarks you want to include
Currently, 132 landmarks are being retained. The following points are being excluded:
- EYE BAGS: 44-49
- LOWER LIP: 99-103
- EARS: 115-124
- HALO: 145-157
- SMILE LINES: 158-163
- CHEEKS: 164-169
- PHILTRUM: 170-173
- CHIN: 174-178
- NECK: 183-184
If you decide to include/exclude different landmarks, you can do so by editing lines 4 and 9.
- Edit **line 4** to change which points you want to retain
E.g., if you wanted to only keep iris/pupil (LMs 0-17) and eyebrow points (LMs 71-86), you would use `'2,19p;73,88p'` to keep the lines 2 to 19, and 73 to 88
- Edit **line 9** to adjust the number of landmarks you are using.
E.g., if you were to keep only the landmarks mentioned above, `"LM=132"` would have to be changed to `"LM=34"`
