Landmark annotation structure

[alex-ertl]

Hello,

thank you for publishing this interesting dataset!

I hat a look at the landmark annotations and have a question on the structue. So for Rater 1 I found in the mat file under 'Results' key the shape (19,6). I assume 19 is the number of cases. For case i, file['Results'][i][0:4] contain (22,3) arrays, assumably for 22 landmarks, 3 coordinates. File['Results'][i][4] contains the case id and file['Results'][i][5] contains either L or R.

• Why are there 4 sets of annotations for each case, for Rater1? Did the Raters annotate multiple times, for intra-rater variability?
• What menas the L or R?

Thank you for your support!

Best regards,
Alexandra Ertl

Hi Alexandra

The easiest way might be to look into and run the following script in case you have MATLAB installed:
https://github.com/MCM-Fischer/VSDFullBodyBoneModels/blob/master/MATLAB/plotManualLandmarks.m

• Yes, the raters did annotate multiple times to asses the intra-rater variability (see https://doi.org/10.1038/s41598-019-49573-4 for further information)
• L = left and R = right side of the body

Let me know if you need further explanation.

Kind regards
