Hi, Margaret:
If you have downloaded the freesurfer release, everything should be included (including MNI software). I guess that the script "recon-all" is not written in the out-dated documentation.
You can do the talairach using the script "talairach2" or line-by-line as follows:
$ setenv LANG C $ cd $subject/mri $ mri_convert nu nu.mnc $ mritotal -protocol icbm nu.mnc transforms/talairach.xfm $ mri_add_xform_to_header transforms/talairach.xfm orig

hi, just to clarify, running this from the command line will create talairach coordinates or do you need to download the additional mni software? and, is this step included in the process volume command when using the csurf interface? thanks, margaret

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
