Dear sir/madam, I try to use TRACULSR to analysis DTI data of GE machine. But when I transfer origin data to nii, I found 2 nii file producted per sample. Can I use these data to run TRACULAR、 If yes, how can I combine 2 nii file? I hope someone can help me. Thank you so much

Did you look at the nifti volumes? Are they 2 sets of diffusion-weighted images? If so, you can concatenate them into 1 volume with mri_concat. You will also have to concatenate the text files that contain the b-values of the 2 scans, and those that contain the gradient directions of the 2 scans. Make sure the 2 are always combined in the same order (for the volumes, b-values, and gradient directions). Then you use these combined files as input to TRACULA.

This is one of my sample. I’m not sure if they can be combined.
