Thanks a lot Nick.
I'll try to convert the AFNI skull strip into brainmask and nu and see if I can resume the pipeline.
I put in the new values for the xfm and ran recon-all again with the notalairach flag.
recon-all -s Nl-TAl-001 -notalairach -all
However, it still quits at the watershed step. I ran another brain where the raw images were dcm and it ran fine so the problem is definitely something specific to this brain.
Nick, I know that autorecon1 ran fine for you so I really have no clue why my machine quits at the watershed step even with the transform you gave me.
Any clues, suggestions?
Thanks a lot,
Anil.
Anil,
Here is the transform (the contents of the talairach.xfm file) that I
generated:
Transform_Type = Linear;
Linear_Transform =
9.265516e-01 5.678305e-04 2.317888e-03 3.736965e-01
-8.173273e-04 8.513330e-01 8.824052e-02 -1.653205e+01
-2.688466e-03 -1.064786e-01 9.460568e-01 1.780552e+01 ;
Remember to use the -notalairach flag with recon-all when you create the
new talairach.xfm file, so that it doesnt get overwritten.
4GB is plenty to run Freesurfer, so it is strange that mri_watershed is
encountering out-of-memory errors.
