Which I took to mean that the dipy and csdsi recon workflows can produce both deterministic and probabilistic tractography outputs. However, in the description of those workflows, it says tractography is all done by DSI studio, which seem to only perform deterministic tractography. Am I misunderstanding the workflow? Is there any way to perform probabilistic tractography on DSI data?
Hi @kjamison, qsiprep definitely supports probabilistic tractography on DSI data. The csdsi workflow will extrapolate the DSI grid scheme to abcd or hcp shelled schemes and then run the mrtrix ifod probabilistic tractography method on your data. Would this work for you? That workflow also does the dsi studio tractography, which is why the docs say “both”
They can be modified to do it. I really like visualizing reconstructions in DSI Studio, which also lets you do interactive tractography. All the dipy recon nodes have a "write_fib": true that you can use to get a DSI Studio file that you can look at, or send it to other nodes like autotrack. Or if you prefer to use mrview you can "write_mif": true.
Yes I do like that about DSI Studio, and the speed! But we definitely want both deterministic and probabilistic tractography, and using MRtrix helps us with harmonization with other datasets.
