Crash when reading CSV files

[GaganBhat]

When I try reading CSV files from the roboRio using Pathfinder.readFromCSV(), the code crashes on the Rio.

Here's the code within the constructor of the class.

exists() returns true and so does canRead(). The absolute path is also correct. When I comment out line 32, the error disappears.

Here's the error from the roboRio console

` true /home/lvuser/StraightForward_left.csv true

Think you could link the trajectory you’re trying to import? I’ve had issues when the trajectory wasn’t mathematically accurate... have you tested a simple drive straight trajectory?

StraightForward_left.txt

Here is the csv file (converted to txt so that github accepts it.)

Was this created using Vannaka’a generator GUI? I think you’re using the “SRX” profile they export... you need to use the “detailed” profile for it to be able to import into Pathfinder code using the read function.

Alright, thanks a ton for that, I will try that right now! And yes, I did use Vannaka's generator GUI.

Thanks for letting me know, the error doesn't occur anymore and everything functions normally =)
