That means that you did not delete it. Delete it with the commands given below and rerun

Hello Douglas,

If I do ls $SUBJECTS_DIR/ben, the T1 image will show up as predicted.

However if I tried to recon-all, the error will pop up.

Many Thanks

    What is your SUBJECTS_DIR set to? What do you get if you
    ls $SUBJECTS_DIR/ben

    Hi Andrew,

    Thank you for your reply. I have tried this command you sent me

    rm -rf $SUBJECTS_DIR/ben

    It indeed deleted the ben folder under the subject directory, but
    when I try to run recon-all for this participant under another
    name, it still responds with the same error.

    I have also tried the same data in another laptop. Also showed up
    the error. Would you say it might be something wrong with the
    data itself? (Although I am quite certain this is the raw T1 data
    which has never been performed any analysis).

    Many Thanks

    Peng

        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.

        best

        *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
