Problem while accessing simulation data

[NotSoCoolLikeYou]

Hello,

when I tried to use the class Simulation to access the simulation data as the tutorial says, I encountered the problem shown in the picture below. The folder MAPIRlab/sim2 in the picture contains the files named like "iteration_x" and also a folder called "wind". I also tried with other simulation folders, and seems like the actual buffer size is always smaller than required. The simulation data are generated by GADEN test_env on ros2 humble, if this information matters.

Also, when using VGR Dataset, although the simulation data can be read, but sometimes there's a problem reading the simulation data from the scenarios with the name "fast" like House04/gas_simulations/5,7-1,2_fast, as shown below in the first picture, the env_min and env_max doesn't seem reasonable (the first dimension of the environment is from -24.9 to 881, which is too big in my opinion). While using the folders named after "slow", like House04/gas_simulations/5,7-1,2_slow, the problem doesn't exist, like shown below in the second picture, all the numbers of env_min and env_max seem reasonable.
