Tract profiles

[raikes....@gmail.com]

Hi Frank,

I'm trying to some tract profiling. I've followed the example commands but it appears that either I'm missing something or the commands have changed without clarity:

apptainer exec /groups/adamraikes/singularity_images/dsistudio_2025-09-11.sif dsi_studio --action=ana --source=sub-001_ses-01_dir-AP_run-001_space-ACPC_model-gqi_dwimap.fib.gz --tract=sub-001_ses-01_dir-AP_run-001_space-ACPC_model-gqi_bundle-ProjectionBasalGangliaCorticostriatalTractL_streamlines.tck.gz --export=report:qa:3:1
