Dear FS experts, I'm interested in doing DTI analysis, using FS.
Do I need to have functional data (feat) and then do I need to register the anatomical data on the functional one? My MRI data contains the following folders: 3DAx_T1, Ax_Flair, Ax_T2PD, DTI_15, DTI_30. I am not sure for a DTI /FSL analysis what data should I use. 1).Do I need to use the DTI data (DTI_15, DTI_30) and what steps should I follow in order to run a DTI/FSL data analysis for my subjects versus controls? 2).Do I need to run the dt_recon? In this case my input should be the dicom images from a DTI (DTI_15 or DTI_30) folder? 3) When I need to check the registration where I get the lowb.nii? tkregister2 --mov dti/lowb.nii --reg dti/register.dat \ --surf orig --tag 4) Or, should I use trac-all on the DTI_15 or DTI_30 data? 5) Do I need to run reg-feat2anat to first analyze my data with FEAT (No Smoothing )as in the example posted online: reg-feat2anat –featdir fbert1.feat –subject bert 6) From where fbert1.feat is coming/how was obtained? Sorry for asking so many/silly questions. I will be greatly appreciate any help/directions/suggestions. Antonella
