That looks like a "design flaw" for NIFTI datasets that contain the "+tlrc" or "+orig" inside them. You can work around this by either moving/renaming the file to one without the offending characters first or by using another command like 3dcalc to copy the dataset:
3dcalc -a antinsula_lr_resampleafni+tlrc.nii.gz -expr a -prefix antinsula_lr_resampleafni
