No reading from CT output file

[DouglasDDL]

Dear all, Previously I used OpenGATE which was ten years ago.

recently I relaunch it and tried to modify the code since version is much different.

However, in my CT output data, while read it via MATLAB, there is no reading inside at all.

Even I used example code from this website, same problem occurs.

I used it one ubuntu virtual box Gate v9.3

Can anyone help me? I have been stuck for 2 month.... Appreciate :)
