Hi - the dyads and pvfs need to be named *exactly* like the FA files, i.e. not "2024_mean_f1samples.nii.gz" but actually "2024_dti_FA_FA.nii.gz"

I copied my dyads and partial volumes to the latter directories. My FA folder contains files named like 2024_dti_FA_FA.nii.gz, and my dyads/ partial volumes are named similarly (e.g., 2024_mean_f1samples.nii.gz). When I run tbss_x from the tbss directory I get errors like this:
