Then, I wanted to use the label of the thalamic nuclei to select an ROI in the MGN and the MD to perform functional connectivity with cortical regions in SPM. Therefore, I converted the outputs of the segmentation (ThalamicNuclei.v10.T1.mgz and ThalamicNuclei.v10.FSvoxelSpace.mgz) into nifti files by using the command "mri_convert .mgz .nii". However, the resulting labels of the thalamus have a different resolution and I cannot visualize anymore the different thalamic subnuclei but only the entire thalamus. Do you have any suggestion to convert thalamic labels into nifti without losing the different subnuclei? Do you think that the thalamic segmentation is accurate enough to be used to perform functional connectivity? Thank you and best regards, Valentina Mancini
