Re: [Freesurfer] Problem of the Mapping Label to the Subject

There is no QDEC in 7.X, we have abandoned it.

Thanks for your help, I have tried FS 7.1.1, while there is no Qdec command when I tried FS 7.1.1 in the terminal window. How should I start the Qdec in the 7.1.1 version.

Best wishes Mengjun Li

I think this is a bug in freeview from FS 6.0.0 that has been
fixed in 7.x. Would it be possible for you to try FS 7.1.1? A
quick workaround you may try first is to change the offset for the
inflated surface to 0 0 0 in freeview 6.0.0.

Best,

    Dear FreeSurfer Developers:

    My name is Mengjun Li, I am a MD in the Second Xiangya
    Hospital, Central South University. I compared the cortex,
    area, volume in the mild traumatic brain injury patients with
    health control by the FreeSurFer and found the problem when
    mapping label to the single subjects.

    There is statistic difference in the area and volume
    between the mild traumatic brain injury patients and the
    health control, I defined the statistic difference region as
    a label on the fsaverage and mapped this label to subjects by
    the Qdec. Although the label defined on the fsaverage was
    mapped onto all subjects successfully,the label in the
    subjects did not match well with the inflated cortex of the
    subjects. At the same time, the volume and area value of the
    label have been extracted in every subject and I found that
    there is no statistic difference between the mild traumatic
    brain injury patients and health control. I have checked the
    segmentation of every subjects and it was a good job done by
    FreeSurFer. Attached figures illustrated the label mapping
    results.

    Figure 1: the label defined on the fsaverage
    Figure 2: the lateral view of the label in the subjects
    Figure 3: the inferior view of the label in the subjects

    I am sending this email for help since I am not sure how to
    fix this problem. Looking forward to hearing your reply!
    Thank you very much!

    Best wishes
