Thanks very much for your suggestion. I found that FSL's probtrackx is probabilistic fiber tracking. And it is really slow, even with parallel computing.What I need is only deterministic fiber tracking. But I found most of deterministic fiber tracking tools don't accept gifti file as seed region. So I am sorry still confused with the question, how to transfer a label.gii file into a volumetric *.nii file for easy use.
Thanks a lot!Lisa From: [email protected] To: [email protected]; [email protected] CC: [email protected]; [email protected] Subject: Re: [HCP-Users] activation region mask Date: Fri, 2 May 2014 05:06:35 +0000 I would recommend FSL’s probtrackx for tractography and you can visualize the results in Connectome Workbench. I’ve never heard of dsistudio, so I don’t know how to help you use it. We don’t provide DSI data, but rather 3-shell HARDI data. Peace, Matt.

You asked it to find the "OTHER" surface, which doesn't exist ("nonexistant structure"). Our data has left and right cortex surface data in it to begin with, thresholding and importing to label doesn't change that. The label name you used in -cifti-label-import is irrelevant to this command. Use CORTEX_LEFT and CORTEX_RIGHT.

I am wondering is there any wrong with my labellist file? because i specify my label to be named OTHER, there is nor CORTEX_LEFT CORTEX_RIGHT in my label file.

However, it outputs gifti files, and if those don't work in your tractography program, you may need to do some additional conversion. Also, if you want gifti label files from a cifti dlabel file, use -label instead of -metric with -cifti-separate.

But happens for this error? Thanks very much for your help.

To get the surface data you need to specify the -metric outputs. Peace, Matt.

The problem was solved by using -cifti-label-import. Sorry for bothering. Here I have another question: I have a label file *.dlabel.nii (created by thresholding the *tfMRI_MOTOR_level2_hp200_s4.dscalar file, in my previous question) I print the information of this file to a txt file, and find there are 14326 nonzero labels. I'd like to change this file into a normal nifti file in mni space, so that I can use it as a roi region for fiber tracking, I use the command "-cifti-separate -volume-all " and change it into a *.nii file, but when I read the file, I find there are only 3256 labels. I dont know why some labels are discarded.
