Dear experts,

I keep getting the following error messages:

WARNING: File 'foothr' was not found or is not a NIfTI file (unknown extension).
WARNING: File 'foobin' was not found or is not a NIfTI file (unknown extension).
WARNING: File 'foomul' was not found or is not a NIfTI file (unknown extension).
WARNING: File 'foothr' was not found or is not a NIfTI file (unknown extension).
WARNING: File 'foobin' was not found or is not a NIfTI file (unknown extension).
WARNING: File 'foomul' was not found or is not a NIfTI file (unknown extension).
WARNING: File 'foomul2' was not found or is not a NIfTI file (unknown extension).

How do I get pass them? I have no problems with preprocessing data in the tutorial pack, but when I try to preprocess my own data set, it just does not work.

Thanks in advance!

Kind regards,
Tinya
