Unable to split_dir in fixel2voxel

Hi everyone,
I am trying to use fixel2voxel to compute angle maps based on specific fixel and have been trying to use the split_dir function as suggested in other previous posts. But the error message indicates that the split_dir can no longer be used.
Can someone please kindly suggest any other function that can be used to compute angle maps or has split_dir been changed into some other terms?

Thank you,

Hi Carol,

I think the command you’re looking for is now called fixel2peaks?

All the best,
