error running the script with my dataset, have I used the flags correctly?;

Sorry for the late reply. It's a busy week... It seems the reason is some slightly difference in NGP json format. I've try to fix it in this PR: https://github.com/wanmeihuali/taichi_3d_gaussian_splatting/pull/110 The PR is now merged, can you try the lastest code?

Hi, I did make a convertor in the end to re-structure the file before running the tool, but I just tested the transforms I supplied you after pulling the updates and that both go through fine now.
