I have been having the same issue as several people. I am a little confused from all the posting as to which file I need to edit when I am getting an error with the tbss_non_FA script.
I would just like to confirm which files I am changing. I have gone through all TBSS steps and I know have 3 folders (FA, origdata and stats). I have added a new folder called MD...added all my MD files (named the same way as my FA files). From what I understand, I need to remove the "FA" at the end of my files. From origidata or FA? "FA" contains the FA files (CON_103_FA_FA.nii.gz) along with several other files obtain from TBSS step 2. Files in "origidata" are called CON_103_FA.nii.gz.
Do I change the name of the files in "FA"? If so would it be from CON_103_FA_FA.nii.gz to CON_103.nii.gz?
Also, after I have changed their name do I leave them in this folder? If I want to re-run some more TBSS analysis will the change in the name have an impact?
Thank you for your advice.
