Hi @aremazeilles,

I'm working on beast and need a data format representing a distance through time.
I considered using the Joint center 3D trajectory or Landmark 3D trajectory data formats, reporting a position in meters through time, but having the x, y and z fields is not ideal since I need to represent a distance rather than a position.

The data is computed as the minimum range between the trolley and obstacles at any time, measured with a lidar/range finder.
I suggest the following data format:

time range
sec m

What do you think?

I see two options:

  • Create a specific format, distance.csv
  • Use the generic format platformData.csv since it can contain any information.

The advantage of the first option is that we know from the file name its content. I don't mind adding such format.
If so , would it make sense to suggest a generic description, such as:

  • if a single distance is recorded, the col label could be distance.
  • If several distances are recorded, the col label should be extended with a landmark name: distance_name1, distance_name2

I would rather use the distance term rather than range, as it describes better the information stored.
Any opinion?

I'm perfectly ok with the distance format, including the option to include multiple columns! I'll update my data format.

@Enri2077 did you use that format at the end? If yes, please point me to your files, and I will adjust documentation accordingly

Yes I used it. I still don't have a definitive dataset, but I'll attach a file using this format:
subject_001_cond_007_run_001_distance.csv.zip

Would #88 make the job @Enri2077 ?
