Hi Africa,
-nonormalization flag skips the step where T1.mgz is generated which is
causing the error, as you mentioned. 001.mgz initiates the recon-all, but
there are several other steps and files generated in the process.
Please refer to this wiki to see which steps and the output at each step.

Hello all,
When I run the function recon-all -subjid s00x -autorecon1 -autorecon2
-nonormalization I've got an ERROR message:

So, when I run the recon-all -subjid s00x -autorecon1 -autorecon2
-nonormalization,as the error message says, a T1.mgz is needed.How can I obtain
the T1.mgz to be able to run this recon-all. In fact, the only file that is
needed to run the recon-all -autorecon1 -autorecon 2 is the 001.mgz,isn't it?
Thanks for your help.

Hello,

-nonormalization I've got an ERROR message:

When I open de mri file of the subject, I realize that there is not any T1.mgz
file, because freesurfer did not generate it. So the question is, when I run
the function recon-all with the -nonormalization flag added, does freesurfer
skip the generation of the T1.mgz file?
Thanks for your help,
Africa.

Yes, that looks okay. You can also add -autorecon3 flag if you want the
dataset to go through the whole recon-all stream.
Thanks,

Hello Sita,
Is this the right way to add the -nonormalization flag to the recon-all
function to skip the normalization step during the first recon-all??:
"recon-all -subjid s00x -autorecon1 -autorecon2 -nonormalization "
Thanks for your help!

You can run recon-all with -nonormalization flag, which will skip that
step.

Hello,
Another question:If during the first recon-all, freesurfer makes skullstripping
and normalization automatically... Is there any way to run the first recon-all
without automatic normalization?
Is it possible?
Thanks
Af.
