Hi Tim,
Thanks for your reply. I used cifti-separate as you suggested to
create volumes from *.dtseries.nii file I have. However, I am having
difficulty to read the resultant file. Is it a cifti file? I cannot read
this file using either ft_read_cifti() or ciftiopen(). Also the file is
huge (1.8 GB). How do I extract time-course from this file?
I created the file using following command:
wb_command -cifti-separate '*.dtseries.nii' COLUMN -volume PUTAMEN_RIGHT
'out_putament_right'
Best
