[BUG] Some runs do not show after being imported #9

Open JonatanGeb opened 3 months ago

JonatanGeb commented 3 months ago

Description I am having a problem where data from multiple runs do not show up after i try to import them. As of now i have encountered this issue for Formula Student TTC Round 5 runs 30, 32, 33 and 33. Runs 28, 29 and 30, for example, seem to work as intended, at least there are numerous rows labelled e.g. run 29 showing up after import. I am new to matlab and this app, but when opening the data-files separately they all seem to be okay.

Reproduce Steps to reproduce the behavior:

  1. Open Magic Formula Tire data app
  2. Go to Tire Data tab, add desired files from my downloads folder to the top right box
  3. Click Run Import
  4. Runs 32 - 34 for example do not appear, run 31 does.

Screenshots If applicable, add screenshots to help explain your problem.

Version of MATLAB

Hi, could you please verify that you are using the RunData files in SI units?

JonatanGeb commented 3 months ago

Yes, I am using the files in SI units. RawData_DriveBrake_Matlab_SI is the name of the folder containing the runs I mentioned earlier for example.

This is what it looks like when I open the data separately in Matlab, Pressure and Fz values seem to be in Pa and N. (Fz in the range of 200 to 1200)

Hello

Now I tried importing the tire data on a Windows computer to eliminate that source of error and I did some experimenting...

Current setup: Windows 10 Matlab R2024a

With version 1.5.1 of the app the problem remained exactly as it was before, only runs 24 and 31 loaded in. With version 1.5.0 of the app all files (24, 25, 31-34) loaded in correctly. However I got the same problem as issue #4 . With version 1.5.0 and with the new parser as posted in the solution of issue #4 runs 32-34 are missing again and I got the following: Fitter

As I am using data from Round 5 of FSTTC I wonder if some variables have the wrong names and if that is something I manually have to change in the parser? Has the way of documenting the tire data changed? Since the old parser works but not the old fitter, and the new parser only seems to care about some of the data and then the new fitter lacks data to do its job.

Hi, you need to use RunData, not RawData.

Also make sure the data you import contains data for the mode you want to fit. TTC exports two RunData sets for each tire (with exceptions). To fit combined slip, you need to load both sets.

Hope that helps Tom
