Re: [Freesurfer] TRACULA bvec bval read from dicom

Hi - If there is no error message in your scripts/trac-all.log file, that means that it was able to read the information from the dicoms. You can double-check if the gradient table was read correctly by inspecting the outputs of the tensor fit with: freeview --dti dmri/dtifit_V1.nii.gz

Dear FS experts,   I’m wondering whether the Monte-Carlo simulation accounts for spatial or intensity thresholds (or both).   Thanks,   Yoichiro Takayanagi___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu

I wouldn¹t trust resting state data that have not been properly denoised. You should only need the structural and FIX cleaned packages for what you are doing. The link that I put below explains how to get HCP data onto the fsaverage4 surface. You will need FreeSurfer and Connectome Workbench for

Matt, Thanks for the quick reply! I'll check out that Wiki document and the 2016 Nature paper first. The reason I have the pre-processed (but not ICA-FIX'ed) rfMRI data is because I would like to use the iterative parcellation algorithm from the Liu Lab @Harvard (as described in Wang, D. et al.

You would be better off resampling the existing CIFTI data to the fsaverage4 surface rather than redoing the projection and smoothing in the volume. Instructions for getting to fsaverage are available here: https://wiki.humanconnectome.org/display/PublicData/HCP+Users+FAQ#HCPUsersFA

Dear LME developer and expert, I am using LME recently, based on longitudinal brain structural data, but I have two confusions in using it. 1) I followed the tutorial at: https://surfer.nmr.mgh.harvard.edu/fswiki/LinearMixedEffectsModels However, I don't actually understand the Contrast

As a work-around to the above issue, I did the registrations directly in FSL using FLIRT, and then converted the resultant fsl reg.mat files to freesurfer reg.dat files (using tkregister2; they all look fine). Now, all I need is to project these rfMRI data to fsaverage4, and I thought mri_vol2surf
