I had got the same error output with v4.50 but not v4.01 for one of my subjects. I guessed that something might be wrong with the skull-strip process. So, I ran this step with different wsthresh values (from 20 to 30, increased by 1), and found that the brainmask looked very similar if the wsthresh value was set as 20-22 (if it was larger than 22, too much non-brain tissue was left in the brainmask). Then, I ran autorecon2. If the wsthresh was 20, no luck; if it was 22, the autorecon2 went through without error.
There were other strange outputs from the skull-strip process for this specific subject (sorry, it is off-topic): when wsthresh=23~30, too much non-brain tissue was left in the brainmask, except for wsthresh=25 (part of the cerebellum was removed).
Hope that this information helps.

Hi Bruce,
There is plenty of disk space, and the 'aseg.auto_noCCseg.label_intensities.txt' file *has* successfully been written to the subject's 'mri' directory.
best, Narly.

Dear all,
I am encountering a problem with 'recon-all -all' with one subject using freesurfer version 4.5 which I did not encounter when using version 4.4. With the older version, the stream ran without error, whereas the processing produces the following error with version 4.5:

I have tried simply rerunning the recon-all -all stream but the error is reproduced consistently. This seems strange since there was no such error with the very same data using version 4.4.
Is there any way to correct for this problem so that the stream can run successfully?
Thanks in advance and best wishes, Narly. _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
