Hi Gunjanyou need to give us more information. What are the two volumes? Why is one "ground truth"? What in general are you trying to achieve?

I have attached both the volumes (reference and input) with my mail.
Its the last step of my work, I'm stuck at and not finding any solution. I
read that FreeSurfer can solve my problem.
I will be obliged if you find some time for this.

Ok I try this out.
Did you answer my Query 1(related to cropped output
of mri_convert command ?
I probably did not understand.

Hi Gunjan
FreeSurfer has been designed to work as a
pipeline. Picking out
individual pieces and running them may or may
not work, and
certainly won't be as reliable. I would advise
you to run
recon-all -all, then you can use the contents
of the subject
directory to do whatever analyses you want
(e.g. generate an
un-bias-corrected, skull stripped volume).
The subject id is one that you make up - it
will be the name of
the directory under which the results are
stored. Also specify a
SUBJECTS_DIR on the command line, which will
be the root
directory under which all the individual
subject trees live
(with -sd <subjects directory path>

Actually, I have two volumes, belong to
the same
subject. One volume is the
ground truth which will be considered as
standard
for the second volume
which is the processed one or the
extracted brain.
To perform a perfect
comparison between both volumes, these
must generate
equal number of slices
in order to compare the corresponding
slide. But
here there is problem with
my volumes, that is while performing
slicing Ground
Truth volume is
generating 360 slice and processed
volume is
generating 181 slides. So
comparison can't take place in this way.
This is the
reason I used
mri_convert command.
If I am not wrong then recon-all command
will do
bias correction as well,
which is not my requirement. What I want
is to have
the binary brain mask
volume and brain volume only. recon-all
command is
asking for the subject-id
and I'm not sure about it. I have gone
through its
documentation but still
not able to run it properly. I request
you to please
help me in this.

Hi Gunjan
you need to give us more details.
What are you
trying to do? Why
not just run recon-all -all? That
will be much
easier than
trying to ru individual steps

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.
[icon_10_generic_list.png]
a.nii
[icon_10_generic_list.png]
b.nii
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,
