[Freesurfer] Two FS versions in different user accounts

2012-01-27 Thread _andreia_
Hi everyone,

I'm sorry to bring this question up again, but I'm thinking to install  
version 5.1 in the same computer where version 5.0 is installed.  
However I'm thinking of installing the new one in another user account  
that I've created only for this porpuse. My question is, can I install  
and work in the new user independently? This way I won't need to be  
changing the subjects dir and the freesurfer environment each time I  
want to work with 5.0 or 5.1, right?

Advice needed =)

Thanks,
Andreia

Hi Andreia

yes, that should be fine. You really just need to change FREESURFER_HOME 
and the associated binary paths to use one version or the other.

[Freesurfer] control point guidance

2012-01-27 Thread Michael Harms

Hi guys,

We are currently trying to fix some errors in the white/pial surfaces
where there are thin white matter strands by using control points, and
are noticing a couple things:

1) The resulting WM surface in the area of the CPs can end up too far
into the GM instead.  Given that, is there any practical guidance for
how to think about the surrounding spatial extent that is impacted by a
given CP?  i.e., How do CP's actually get used within mri_normalize in
an algorithmic sense?

2) The surfaces are being impacted in places distant from the CPs.
e.g., CP's placed in the left anterior temporal lobe are resulting in
surface changes in the right anterior temporal lobe.  And when I
difference the original norm.mgz vs. the one obtained after using CP's,
I'm seeing an odd pattern of intensity differences which is clearly not
limited to just the area of the CP's (which would be my expectation).

This is version 5.1.

thanks,
-MH

Hi Michael,
I had the same problem too. It might be because of the type of scanner you
are using. I added -washu_mprage flag, it pretty much helped me (I did not
had to add a lot of controls points and so on so forth. You can go through

Hello Rashmi,

This is an AFNI issue. You'll have to read the SUMA manual and convert 
your Freesurfer files to AFNI-readable surfaces using @SUMA_Make_Spec_FS 
and other commands. There are too many steps to list here, but it is not 
too difficult once you get the hang of it.

Re: [Freesurfer] control point guidance

2012-01-27 Thread Bruce Fischl

Hi Mike

it's a bit hard to state the region of effect for the control points. 
Essentially we go through and label voxels as control points or not based 
on their intensity, intensity gradient and connectivity (that is, the must 
be 6-connected to other control points) then build a Voronoi diagram and 
each control point sets the scaling for its Voronoi triangle. Thus if you 
have a control point surrounded by others its region of effect is small, 
but one control point all by itself can have a large region of effect.


Also, 5.1  applies the manually specified control points to the aseg 
normalization (norm.mgz), whereas older versions didn't. Not everyone is 
happy with this, so I think there is a backwards compatibility flag. Nick 
would know.

 above, doesn't the --fstal flag use the talairach template?  But
 shouldn't it be using the 711 template?  And since I am using fs5.0.0,
 does that mean that I should not be using the RB template?
 Ultimately, what is the correct way to verify the ICV in fs 5.0.0?

 Thank you for the idea.  I did this, and got a much better icv.  On fs3,

Hi Jeff,

I am not sure about which atlas, but concerning the transforms:

4.2 and earlier: talairach_with_skull.lta
later versions: talairach.xfm

I am pretty convinced that the way to check as described here
http://surfer.nmr.mgh.harvard.edu/fswiki/eTIV

cd $SUBJECTS_DIR/subject/mri/transforms
tkregister2 --xfm talairach.xfm \
  --targ $FREESURFER_HOME/average/RB_all_withskull_2008-03-26.gca \
  --mov ../nu_noneck.mgz --reg junk

is correct in newer FS versions, but maybe double check with Nick.

  is having problems.  040002_S04 is from fs3 and has a good icv value.  
  Some
  of the blank spots are from my graphics drivers and unrelated to fs.
   tkregister2 also said the determinant of 040002_S04_test was 1.49544.
 
  Martin,
 
  Thank you for the idea.  I did this, and got a much better icv.  On fs3,
  where the icv was good, the number was 1,767,481.  On fs4, it was 
  1,302,696.
   Using your idea on fs4, it was 1,819,485.
 
  Thank you so much to everyone for your help!
  Jeff

 Hi Jeff,
 
 I see this relatively often. Eventhough the talairach registration
 is fine, the
 ICV is underestimated. In this case I take old ICV, which helps.
 
 mri_segstats --subject $MYSUBJECT --old-etiv-only
 
 This is in 99% of these cases a cure. This is not just a blind
 attempt. In
 these cases I then compare each ICV normalized aseg volume against
 an age
 matched group and only if the old-etiv-only ICV gives better
 estimates I use
 it.
 
 Cheers,
 
 Martin

  Thanks Doug.  That is very good news to hear!
 
  Maybe I spoke too soon about fixing the problem.  I looked at 4 more
  subjects, and even though the icv value is unique, its magnitude
 seems
  wrong.  Often times, it is smaller than the BrainSegVol, which
 doesn't make
  much sense and it is also low overall.
