Hi Peng,

Are you sure you’re deleting the subject folder from within the SUBJECTS_DIR?

rm -rf $SUBJECTS_DIR/ben

Should clear the issue.

Subject: [Freesurfer] Error with recon-all: You are trying to re-run an existing subject with (possibly) new input data (-i).

        External Email - Use Caution        

Dear all,

I am trying to run recon-all command for a subject ben. Before I perform this command, I have exported SUBJECTS_DIR to a folder with only T1 data for this subject ben in it. However after I entered the command "recon-all -s ben -i T1.nii -all", this error showed up:

ERROR: You are trying to re-run an existing subject with (possibly)

new input data (-i). If this is truly new input data, you should delete

the subject folder and re-run, or specify a different subject name.

If you are just continuing an analysis of an existing subject, then

omit all -i flags.

I have tried all the suggestions listed in the error information, but none worked.

Does anyone have any suggestion? I would really appreciated it.

Many Thanks

Peng
