Hello Dear Freesurfer Developers,

I am attempting to run Tracula in the last to subject of my study (I had processed all the other subjects using the same script without problems). However, when I try to run the scrip bellow, I am having the error:

" ERROR: Must specify input table of gradient vectors "

 I am reviewed the associated DICOM images and couldn't find any problem with the images. I reviewed a couple emails in the list, but couldn't find a clear reason for keeping having this error.

I am using the Freesurfer Dev version.

I really appreciate any help.

Thank you, Gabriela
