Hi, Margaret

The head is tilted almost 10 degrees. This makes it difficult to cut the brain into two.
You really need the talairach transform or any other transform to straighten up the head to
find the cutting planes.


I just copied your volume and ran recon-all -stage1 and "mri_fill" created a very clean filled
volume.

Hi,  I tried to manually set the cutting planes, but I was unable to get
the create surface to run.  My subjects info is at
/space/troy/1/users/FREESURFER/SM2S4_freesurfer and I tried to specify
coordinates (121 90 139) for the CC and (131 159 118) for the pons.  I
used the manuals troubleshooting to guide me, but is still cannot find
them.  The logfile I got is below.  Could something besides
specifying these coordinates be going wrong?  Thanks, Margaret

Hi Margaret,

if no talairach.xfm exists, then the fill may still find the cc and pons,
but it might not. You can always specify them manually be finding a
sagittal slice in which the cc is disconnected and a horizontal slice above
the cerebellar peduncles where the pons is disconnected.

cheers,
Bruce

The log file is below.  And at the end it says command finished, not that
something went wrong.  I am not sure about the cutting planes or how to
specify them manually.  Thanks for your help.  Margaret

Hi Margaret,

we need more information than that. Can you send us log files from trying
to run mri_fill? Is it finding the cutting planes? Have you tried
specifying them manually?

cheers,
Bruce

Hi,  I keep getting an error message after I run Create Surface.  It is
similar to questions found in the archive but those solutions did not work
and this problem did not occur for the first 2 brains I reconstructed.  I
get an alert that the Images (filled): /subjectsdir/mri/filled/COR-001 not
found.  wmfill first.  I thought the first step was to fill the wm so
these files should have already been created.  Thanks for any help,
Margaret
