@miranov25 , this adds to the unbinned residuals tree a branch with 4-bytes struct https://github.com/shahor02/AliceO2/blob/6c23010c8442f96250eb35358bd3c73ca04a9723/Detectors/TPC/calibration/SpacePoints/include/SpacePoints/TrackInterpolation.h#L104-L145 encoding the TPC dedx, TRD q's and slope (truncated to +-3.5 range), TOF cluster time wrt track ITS-TPC time and the same for the PV (i.e. one should use the relevant getter depending on the row value).
I've copied residuals for 1 ctf of OO/564356 to /alice/cern.ch/user/s/shahoian/toMI/o2residuals_tpc.root.
Hope the dump below is self-explanatory:

Hello @shahor02

Thank you.
I assume that detInfo.word is parallel to res – we have as many detInfo entries as residuals.
I am now checking the context.

If my understanding is correct, then it will work.
I have one more question.
I need to define the occupancy.
In the current residuals, we have neither occupancy nor time. What is the best way to add them?
I am considering the occupancy vector we have in the reconstruction, but we will need to assign time to the track to be able to use it.

In meantime I will check your file
