[Freesurfer] One sample t-test in Qdec

2014-03-05 Thread Buse Merve Ürgen
Hello,

I would like to learn whether we can conduct one-sample t-test using Qdec.
I'm working on a single-case study, and I want to compare a single
subject's data with a group of controls (to see how this specific subject
is different from the group) in terms of volume, thickness and
meancurvature. As far as I know, we can do the analysis in Terminal, but I
would like to see  have the brain figure output (cluster by cluster) in
Qdec for one sample t-test as well. Is it possible?

Thanks in advance,

Buse.

[Freesurfer] Combining sagittal and axial T1 for volumetric analysis

2014-03-05 Thread Tartaglia, Carmela
I have patients and controls scanned on the same scanner but their data was 
acquired in different orientations. One group is sagittal and the other is 
axial. The sizes are 1X1X1 vs 1X1X1.2. Is it possible to combine these images 
for freesurfer analysis?

Thanks

Hi Carmela

are all controls scanned with one protocol and all patients with another? 
If so, combining them and interpreting the results is going to be 
difficult.

Dear experts,
our group decided to make all the white matter edits in brainvoyager (don't ask

the recon-all -autorecon2-wm … and found massive reduction in the thickness. So 
far so bad.
To figure out the problem we started at the beginning of the conversion-mess 
and converted the wm.mgz into wm.nii and back into wm.mgz and found nearly the 
same reduction in the thickness. Finally, here comes my question. Is it 
possible that due to interpolation errors in the mri_convert routine this 
reduction can be explained?
PS: here is the output from mri_diff for the wm_orig.mgz and the converted one: 
Volumes differ in geometry row=1 col=1 diff=0.00 (5.96046e-08)
Please fin attached the reconstructed white matter surface (red = original,

Hello Michael,

Use the Freesurfer Centos4 build for your Centos5 platform. People who
want to take advantage of of multiple cores typically use the -openmp
num cores flag when running recon-all. Theoretically the more cores
you use the faster the runtime, but we have found that that there is
little gain after 8 and when using that many we typically only see a 25%
decrease in the time it takes to run the entire recon-all stream.

You could try and get fancy by writing up a script and breaking up the
reson-all stream into parts and parrallelizing some of the processing of
the left and right hemispere... something along the lines of:

recon-all -s subj -autorecon1 -openmp 8

 I appreciate greatly your time and thank you very much in advance,

[Freesurfer] extract pial_lgi from v1.thresh labels

2014-03-05 Thread krista kelly
Hello,

I would like to extract the pial_lgi data from Freesurfer's V1.thresh
labels but can't quite figure it out. I've tried adapting the commands from
the LGI Freesurfer tutorial as such:

mri_segstats --label-thresh BV20 lh V1.thresh.label --i
$SUBJECTS_DIR/BV20/surf/lh.pial_lgi --sum lh.V1.thresh.label.stats

I've also tried

mris_anatomical_stats -l lh.V1.thresh.label -f
BV20/stats/lh.V1.thresh.label.stats BV20 lh pial_lgi

but I've had no luck with either.

I would appreciate any help!

Thanks,
Krista

  I also have another question: I have loaded a subject with tkmedit,
  but the segmentation looks drastically improved when the
 -segmentation
  is aseg.auto_noCCseg.mgz instead of -wmparc.mgz (images attached),
  though the pial surface does not reflect this.
 
  Could you tell me why this is? And is it possible to get the pial/wm
  surfaces to follow along the lines of the aseg.auto_noCCseg.mgz
  segmentation? I am sorry if this is a naive question.
 
  Also: the images are from the original aseg.auto_noCCseg.mgz of this
  subject (MPS2002-3), not the updated one you sent me, Bruce.

Re: [Freesurfer] extract pial_lgi from v1.thresh labels

Hi again,

My apologies for the barrage of emails! I was able to do mri_segstats on V1
labels for pial_lgi using the following:

mri_segstats --label-thresh .5 --slabel $s lh

$SUBJECTS_DIR/$s/stats/lh.V1.thresh.label.LGI.stats

annotation (

and tried to adapt to the labels. Here is what I've tried:

Hello,

Is there any way to extract a three dimensional coordinate representation of 
the different brain regions (i.e., their centroids) that freesurfer is 
estimating the cortical thickness of?

Any help is appreciated and apologies if this question has been answered before.

Re: [Freesurfer] extract pial_lgi from v1.thresh labels

2014-03-05 Thread krista kelly
Thanks Doug! I did that and it worked, but now here's another problem: the
values that I obtained for V1, V2, and cortex for each subject are all the
same. For example, BV20 left hemisphere values for V1, V2, and cortex are
all 2.7241 (same thing happens for the right hemisphere). Maybe I can tell
you what I did step by step to see  if you can find where I went wrong.

First, I did a for loop to run mri_segstats for each participant for each
label per hemisphere (here is an example of V1):

foreach s (BV20 BV21 BV22 BV23 BV24 BV25 BV26 BV27 BV28 BV29 BV30 BV31 BV32
BV33 BV34 BV35 BV36 BV37 BV38 BV39 BV40 BV41 BV43 BV44 BV47 MB07 MB08 MB09
MB10 MB11 MB12 MB13 MB14 MB15 MB16 MB17 MB18 MB19 MB20) hit enter
mri_segstats --label-thresh .5 --slabel $s lh
$SUBJECTS_DIR/$s/label/lh.V1.thresh.label --i
$SUBJECTS_DIR/$s/surf/lh.pial_lgi --sum
$SUBJECTS_DIR/$s/stats/lh.V1.thresh.label.LGI.stats  hit enter
end hit enter

for left V2 I ran:

foreach s (BV20 BV21 BV22 BV23 BV24 BV25 BV26 BV27 BV28 BV29 BV30 BV31 BV32
BV33 BV34 BV35 BV36 BV37 BV38 BV39 BV40 BV41 BV43 BV44 BV47 MB07 MB08 MB09
MB10 MB11 MB12 MB13 MB14 MB15 MB16 MB17 MB18 MB19 MB20) hit enter
mri_segstats --label-thresh .5 --slabel $s lh
$SUBJECTS_DIR/$s/label/lh.V2.thresh.label --i
$SUBJECTS_DIR/$s/surf/lh.pial_lgi --sum
$SUBJECTS_DIR/$s/stats/lh.V2.thresh.label.LGI.stats  hit enter
end hit enter

and for left cortex I ran:
foreach s (BV20 BV21 BV22 BV23 BV24 BV25 BV26 BV27 BV28 BV29 BV30 BV31 BV32
BV33 BV34 BV35 BV36 BV37 BV38 BV39 BV40 BV41 BV43 BV44 BV47 MB07 MB08 MB09
MB10 MB11 MB12 MB13 MB14 MB15 MB16 MB17 MB18 MB19 MB20) hit enter
mri_segstats --label-thresh .5 --slabel $s lh
$SUBJECTS_DIR/$s/label/lh.cortex --i $SUBJECTS_DIR/$s/surf/lh.pial_lgi
--sum $SUBJECTS_DIR/$s/stats/lh.cortex.LGI.stats
end hit enter


This is where the problem must be occurring since all files created during
these commands show the same files per hemisphere. I've attached three
files created during mri_segstats (left V1, V2, cortex.stats) for one
participant. I've also attached files created during asegstats2table to
show how all values are the same for each label for all participants (V1,
V2, cortex.LGI.txt).

If anyone has any insight into the problem, that would be great!

Best,
Krista

[Freesurfer] Running Tracula on a cluster

2014-03-05 Thread ebelleau

Hello,

I plan on running a batch of subjects (around 80) on a computer cluster.

I am assuming that in the dmrirc configuration file, I can enter all of the 
subjects in subjlist?

However, do I have to add something to it to make sure that each subject gets 
sent to a different processor on the cluster?

I have attached my dmrirc file as well as the files needed for it to run on the 
cluster.

Thanks,

Emily

Hi Anastasia,

We use SLURM.  

I have not personally yet run bedpost off of the cluster, but one of my 
colleagues was able to run his data off of our cluster ( the whole pathway 
including bedpost) without any problem. However he (Jon Wieser) made an 
individual dmrirc configuration file script for every subject and then made 
sure each one got assigned to a different processor in another script. 

Thanks,

Emily

Re: [Freesurfer] extract pial_lgi from v1.thresh labels

2014-03-05 Thread Douglas N Greve

Sorry, I gave you some bad advice. Only use --label-thresh with labels 
that have a statistic that is non-zero (this is the last column of the 
label file). Eg, in lh.V1.thresh.label, the stat is always 0 (but it is 
non-zero in lh.V1.label). The stat is the probability that the vertex is 
in the label, so you can choose the threshold based on that. The 
lh.V1.thresh.label is for when the stat is the max for V1 relative to 
the other labels (eg, V2). If you select thresh=.5, you may miss places 
where V1 is the most likely but still less than .5. I would probably use 
lh.V1.thresh.label (and then do not spec --label-thresh)

 mri_segstats --label-thresh .5 --slabel $s lh

 $SUBJECTS_DIR/$s/surf/lh.pial_lgi --sum
 $SUBJECTS_DIR/$s/stats/lh.V1.thresh.label.LGI.stats

 However, now I'm having trouble with bringing all of the data
 into one table using aparcstats2table. I found online how to
 get the data for aparc annotation
 
 (https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2013-September/033069.html)
 and tried to adapt to the labels. Here is what I've tried:

 aparcstats2table --subjects BV20 BV21 BV22 BV23 BV24 BV25 BV26
 BV27 BV28 BV29 BV30 BV31 BV32 BV33 BV34 BV35 BV36 BV37 BV38

 MB13 MB14 MB15 MB16 MB17 MB18 --hemi lh --meas thickness
 --parc V1.thresh.label.LGI --tablefile lh.V1.thresh.label.LGI.txt

 I get the following output when I do this:

[Freesurfer] Group comparisons

2014-03-05 Thread Tudor Popescu
Hello, I have some questions on doing group comparisons with thickness,
area and volume. Many thanks in advance for any help!

1) For a DOSS design with group and gender as categorical factors, I see
that an interaction contrast (Is there a group-gender interaction in the
mean thickness?) still exists - but what does this contrast mean, given
that DOSS by definition doesn't allow for interactions?

2) it makes sense that measures such as thickness are analysed vertex-wise
in QDEC, however what does it mean when the dependent variable is area or
volume - measures that do not make physical sense for a single vertex but
only at the level of a region consisting of *several* vertices?

3) For values extracted from atlas regions with aparcstats2table, it seems
that the product of the extracted CT and area is in the same order of
magnitude as the extracted volume, but never really the same or even close
- why, when the volume of a region should theoretically be the product of
its surface area by its thickness?

By default, the surface area is computed from the white surface (ie,

Re: [Freesurfer] Group comparisons

On 3/5/14 5:25 PM, Tudor Popescu wrote:
Hello, I have some questions on doing group comparisons with 
thickness, area and volume. Many thanks in advance for any help!


1) For a DOSS design with group and gender as categorical factors, I 
see that an interaction contrast (Is there a group-gender interaction 
in the mean thickness?) still exists - but what does this contrast 
mean, given that DOSS by definition doesn't allow for interactions?
Are you using QDEC? If so, don't use the DOSS as the contrasts are 
incorrect. It is possible to have an interaction among the categorical 
factors with a DOSS.


2) it makes sense that measures such as thickness are analysed 
vertex-wise in QDEC, however what does it mean when the dependent 
variable is area or volume - measures that do not make physical sense 
for a single vertex but only at the level of a region consisting of 
*several* vertices?
The interpretation is a little more difficult. Each vertex is assigned 
an area equal to the average of the triangles adjacent to it. This is 
just a value that can be mapped to a common space like any other value 
(eg, thickness) (but there is a special jacobain correction to account 
for stretching or compression). Smoothing reduces the effect of having 
different sized triangles. One can think of it like this: in the common 
space (fsaverage) image having a patch of a certain size. When you 
mapped that patch back to each individual, how big would that patch be? 
You could then do group statistics on that number. In this way you could 
analyze the entire hemisphere. Now imagine doing this but making the 
patch smaller and smaller.


3) For values extracted from atlas regions with aparcstats2table, it 
seems that the product of the extracted CT and area is in the same 
order of magnitude as the extracted volume, but never really the same 
or even close -- why, when the volume of a region should theoretically 
be the product of its surface area by its thickness?
It is an issue of how it is computed. Sum(CT*Area) != Sum(CT)*Sum(Area). 
When computing volume, CT*Area is computed for each vertex then summed 
across vertices.

five surface (i.e. anterior, posterior, left, right, interior) are 
excluded ?

Thanks!

By default, the surface area is computed from the white surface
(ie, boundary between WM and GM). It is possible to compute it
from the pial surface (ie, boundary between GM and background)

Hi all,
I need to know how is the SurfArea in ?h.aparc.stats calculated
by FreeSurfer? Since each cortical parcellation has its own
thickness in 3D space, does the surface area computation consider
both the exterior surface (i.e. the surface separating the gray
matter and the background) and the interior surface (i.e. the
surface separating the gray matter and the white matter)?
Thanks!
