Re: [Freesurfer] ERROR selxavg-sess

2010-07-07 Thread Doug Greve


Hi Keta, this is a pretty old version. Are you sure you don't want to
upgrade? The ipr is the "in-plane resolution" stored in the seq.info
file in the bold directory. Newer versions don't use this anymore.

[Freesurfer] Freesurfer file

2010-07-07 Thread wen miao
Hello, Freesurfer experts

I'v got a work with the freesurfer files. As we all know, there are many
files in the freesurfer subject directory, and each file has its usage. My
question is, what's the particular usage for each of these files and how can
I read these files using Matlab or any other softwares rather than the
freesurfer tools? Is there a list for this?

Thanks in advance.

[Freesurfer] probabilistic white matter mask

2010-07-07 Thread Mehul Sampat
Hi Folks,

I believe that I can create a binary white matter mask using
"mri_wmfilter".

I was wondering if there is a way to create a probabilistic white matter
mask ?
(for each voxel, I would like to obtain the probability of it being white
matter)

I did a search on the mailing list and found the following related message:
http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg11786.html

The message suggests to use "-write_probs" flag with the mri_ca_label
command but I dont see this flag as on option in the usage instructions for
mri_ca_label.
If this is the right way, should i just add "-write_probs wm.mgz" to
mri_ca_label to get a probablistic white matter mask ?


Thanks
Mehul

[Freesurfer] editing labels in tksurfer

2010-07-07 Thread Keefe, Helen L
Hi Everyone,

I remember a post in March when Allison referred someone to this page:

https://surfer.nmr.mgh.harvard.edu/fswiki/tksurfer_labeledit

and I think this will be really helpful for me if I can figure out how
to make it work.  I have a scan with corpus callosum bleeding into the
caudalanteriorcingulate.  When I try to change the label, I am able to
select the region by clicking on it.

However, when I try to "Draw a complete outline path that encloses the
desired "incursion"", every time I click to draw the path, the image
refreshes.  

Here are the instructions:

"Create outline path:

*

  Possibly start with Edit > Unmark all vertices
*

  Make a series of clicks along the desired outline path. tksurfer
shows marked vertices."

Is "create outline path"  the same as "Make Path" on the TkSurfer tools
box?
What would make the decision between "Possibly start with Edit > Unmark
all vertices" and not doing that?

I succeeded once in getting the path drawn, but have no luck replicating
that.  Also, when I tried to relabel the part inside the path, I was
able to turn it into label = "None" or turn 90% of the brain into
caudalanteriorcingulate.

I'm missing something really simple here - help, please.

Also - can this be done also on the pial surface using this command?  I
can see the boundaries better on this view than on the inflated

tksurfer $i lh pial -annotation aparc

Thanks for any help - let me know if you need more information

Hello,


I've just started using freesurfer. I've reading the mail list wich helps me
a lot, but
I can't find how I can obtain a table with the values of my glm analysis.
For exemple, in the Qdec's tutorial I have a surface that answer the
question "Does
the correlation between thickness and age differ from zero?" It's possible
to see this data like
a table:
region   mean sdp-value
precentral   xx x   

Or at least obtain those values individually?

Hi Krish,

Thank you for your reply.
Unfortunately none of these did work (but now I've an up-to-date environment
at least).
But the IT/research engineer in the lab found that it was "just" my
environment PYTHONHOME and PYTHONPATH which were pointing at a bad
directory.
After unsetting these two env, it works perfectly fine.

Thanks for your help,

Hi Gaelle

This seems to be an error due to Python's "warning" module being  
deprecated in Python 2.6. I'll update the sources so as to accommodate  
this change.

Meanwhile, the quickest fix is to open up

nano $FREESURFER_HOME/bin/asegstats2table

and comment out the following lines ( put a "#" at the start of the  
line ).. i.e change

import warnings
warnings.filterwarnings('ignore', '.*negative int.*')

to

#import warnings
#warnings.filterwarnings('ignore', '.*negative int.*')

and see whether it works.

Best
Krish

if the talairach is correct (you can verify this in tkmedit or tkregister2)

Hi Salem,

yes, you can run any individual options in recon-all. See the -help output 
and run it through step 11 if you want. Note that we do use the surfaces to 
improve the aseg accuracy at the very end, so you'll be giving that up.

[Freesurfer] RV: FREESURFER

2010-07-07 Thread SANTIAGO GONZALEZ CALERO

> Good morning,I am working on brain segmentation using freesurfer
program.
> I wonder if it is possible to turn an initial image with some tool
freesurfer. Because my problem is that when I start to perform
segmentation in freesurfer, I get an error and I think that is because
dicom image format is a little crooked. If you can not rotate with
tkmedit or similar tool.

[Freesurfer] subcortical segmentation

2010-07-07 Thread Hannoun
 

Hi,

I am a new user of freesurfer. Is it possible to do just the volumetric
processing stages without the surface processing stages?

In fact what I want is to segment the subcortical structures.

Is there a command line for this purpose only or should we run all the
recon-all steps?

Thank you for your help

Salem
