Hi,
I am facing few issues. I will be thankful if you can help me out.*
*
*
Query 1)* I used "mri_convert a.nii a.resliced.nii -rl b.nii" in order
to generate slices so that comparison may take place properly. The
command ran properly but generating cropped slices.
I am attaching the input volume, reference volume and the cropped
slice screenshot.
a.nii
<https://docs.google.com/file/d/0Bx9eWoN_LLBZZ3lnUWstQXdJUzQ/edit?usp=drive_web>
b.nii
<https://docs.google.com/file/d/0Bx9eWoN_LLBZLWZkaC1BNW5abEE/edit?usp=drive_web>
*Query 2)* For skull stripping I ran below command
bibl04@BIBL04:~/Desktop/freesurfer/bin$ recon-all -i a.nii -autorecon1
and its showing error for subject id. I am really not aware, what to
write.
ERROR: must specify a subject id
*
*
*Query 3)* I did not find that which option from (1 to 31 ) should
generate the "binary brain mask".
Thanks,
Gunjan

I will be thankful if you could let me know about the link
related to
recon-all, in order to know about the parameters(input
volume info etc)
associated to it and other usage.

I will be thankful if you could tell me about
getting brain mask and
performing skull stripping otherwise I'll have to
wait for 12 hours to get
your replies as our working hours doesn't match.

Gunjan, this may be related to an Ubuntu
specific issue we
address on
the Freesurfer download page:
https://surfer.nmr.mgh.harvard.edu/fswiki/Download
Specifically the part thats states the
following:
***
On Ubuntu, you might have to do this if qdec
or freeview
complain about
libjpeg or libtiff:
cd /usr/lib (/usr/lib/i386 or
/usr/lib/x86_64
on some Ubuntu
distros)
sudo ln -s libjpeg.so.8 libjpeg.so.62
sudo ln -s libtiff.so.4 libtiff.so.3
