Your questions are too vague to answer. To make any progress, I need to know at least

- how did you create the original input to 3dIntracranial?
- how are you running AFNI? what command line? what text output does AFNI show?
- are you in the correct directory?
- what do you see when you run AFNI and open an image viewer window?
