Problem Generating 3D Plots

[xtian26]

Thank you for the great work you put into TractSeg.

I was running plot_tractometry_results and I am able to produce the graphs where significant difference among subjects are along the tract.

I want to see it on a 3d plot so I tried it but it returns the following error:
ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (1000,) + inhomogeneous part.

I registered my images to MNI space as suggested in the documentation. I also tried changing the number of fibers, but it won't still work and would return the error. Any help would be greatly appreciated. Thanks!

Were you able to find a solution to this problem? I am getting the same issue

Hi! I was able to resolve this in a surprising way. I am running the plot_tractometry_results in an Ubuntu 24.04 LTS. 1 thing I can remember I did was updating the dependencies, viz: Numpy: 1.23.5 Scipy: 1.11.4 Fury: 0.11.0 This was not working in a terminal at first. I tried to open my script(automating the writing of the text file for tractometry results) and tried running the code from the terminal in Visual Studio. It worked and suddenly it was also working for my terminal. I'll try to look into it and will add details to this. Thanks!

Thanks for sharing, this was super helpful for my debugging. It turns out the --plot-3D metric flag no longer works for newer version of numpy. I downgraded from 1.26.4 to 1.23.5 and I was able to output the 3D plots. Appreciate the amazing work by the devs and this useful thread!
