Missing/Incorrect Tract Segmentation

[Luie Wang]

Dear AFQ community, 

I'm trying to use AFQ to segment Arcuate Fasciulus in a group of participants. The automatic fiber segmentation works well for most of the participants but not for all. Some participants' segmented Arcuate Fasciculus is incomplete and off in location. I have attached the pic of a good example and an incomplete one. All participants are acpc aligned via vistasoft and their whole brain tractography were generated in the same way through MRtrix. I also checked the ROIs for the incompletely segmented tracts and they seems to look fine. Does anyone know what could be the possible causes for the incomplete fibers and the inconsistency in tract quality across participants? Thank you so much in advance!

Best,

Luie

Dear Sir，

I have whole brain tractography from Mrtrix and I'm trying to use AFQ to segment it.

But I can not create a write dt6 file. It seems that you had already done it. I will have great appreciate if you can give me some advice!
