Hi Corinna,

the 001.mgz is the first file created in the cross sectional stream (when you import your dicom) it is the input image to the stream and just the dicom converted into mgz format. If it is corrupted, you should rerun this cross sectional time point (just to be safe), the base and the all the long runs.

Best, Martin

Hi Martin,
Neither freeview nor tkmedit could open the 001.mgz file. It could not read 262144 bytes at slice 4. At this point is my best option to re-run this time point from the beginning?

    Hi Corinna,

    try to open
    
/home/Documents/longitudinal_morph/meta/test_subject_2ndpostop/mri/orig/001.mgz

    in freeview to see if maybe the file is corrupted.

    Best, Martin

    Hello,
    I am on the recon-all -long step of the longitudinal processing

    I still have plenty of space left on the drive

    Any suggestions? The two previous timepoints finished without error.
