Re: [caret-users] About Monkey to Human Deformation

2007-03-14 Thread Reza Rajimehr
Dear David,

In the Apply Deformation Map dialog box, I specified the following items:

1) Deformation Map File: the 23-LDMK deform_map file
2) File Type: Metric
3) Flat Max Edge Length: 10.00
4) Metric Deformation: Nearest Node (not sure which one is better?)
5) Smooth One Iteration (Except Flat)

The other buttons were not clickable (the dialog box does not allow me to
use them).

When I click the Apply button, I immediately receive the following error
message:

Deform Error
Is deformation map file valid? You must select a data file for
deformation. You must select the output name for the deformed file.

I tried to apply deformation map from two different .spec files:

1) Macaque F99 atlas directory, which has deformed metric files (from
individual macaque to F99). I added/appended the .deform_map file to this
.spec file before applying deformation.

2) COMPARE_MACAQUE_HUMAN directory (as a part of CARET_TUTORIAL_SEPT06
directory). I added/appended my metric files to this .spec file before
applying deformation.

In both cases, I got the same error.


Thanks for your helpful comments/suggestions,

user to select one specific data file for deformation, it does not

[caret-users] Monkey Atlas and stereotaxic

2007-03-14 Thread Remya Nair

Hi Caret-Gods...!

I have a question regarding Caret and monkey atlas. I apologize for  
the basic nature of these questions, but I am a newbie to Caret and  
that is all i have to say in my defense!!!
We have T1 weighted 0.5 isotropic resolution anatomical images of  
monkey brain. The final aim is to be able to reconstruct surfaces as  
well as find the co-ordinates of points of interest w.r.t our  
stereotaxic coord system. We are working with the inter-aural  
stereotaxic system.
Ideally, apart from viewing the surface , we will need stereotaxic  
coordinates to know exactly where the AP0 is, mediolateral  
coordinates etc.
I have ,as per the Caret segmentation tutorial, segmented the volume  
and created the surfaces. But, the way i have done it, the volume has  
been centered at the AC (as per the tutorial instructions). What  
should I do to center it to the inter-aural origin? is there any  
caret documentation on this... if yes, could you please point me to  
them? Consequently what would be the next steps I should perform  
(perhaps registration?) to be able to read off the stereo-coords of  
interest as per my coordinate system? Please do point me to the  
appropriate tutorials/spec files that i may need.


Thanks in advance!!

Re: [caret-users] Monkey Atlas and stereotaxic

2007-03-14 Thread Donna Dierker

Hi Remya,

Glad to hear you got your hands on a T1 scan.

There's no documentation I know of that covers what you want to do, but 
it's not that hard (if I understand it correctly).


I think you'll just need two versions of your volumes (one AC-centered, 
one inter-aural) and two versions of your fiducial surface (ditto).  
You'll need the AC-centered volume to create your fiducial surface, 
which also will be AC-centered.  When you're happy with your AC-centered 
surface, then translate both volume and surface back to inter-aural.


The hard part is calculating the x,y,z translation offsets between the 
AC-centered origin and your inter-aural origin.  Sometimes it takes a 
sign flip or two to get it right, but only you can compute the magnitude 
of these shifts.  I'll call them shiftx, shifty, shiftz.


Change your volume back to inter-aural like so:

Volume: Edit volume attributes: coordinates: origin: Adjust x,y,z by 
shiftx,shifty,shiftz.  After applying change, hit toolbar: R (with 
volume view in main window) to reset the volume to the new origin, to 
make sure it's correct.  This may take trial and error to get the sign 
right.


Once the volume view accurately reflects the inter-aural origin, save 
the translated volume: File: Save Data File: volume files: NIFTI (or 
AFNI or SPM/MedX, which is basically Analyze): my_interaural.nii


Now, translate your surface:

* switch to fiducial view in main window
* Window: Transformation matrix editor
* Translate: enter shiftx, shifty, shiftz (again -- sign-flipping as needed)
* Apply matrix to main window

In this case, if you get it wrong, then you'll need to use Toolbar: spec 
to reload the fiducial after each trial, to get back to the original AC 
origin.


Once you get it right, use File: Save data file: coord file to save the 
translated coord file as a name like my.fiducial.inter-aural.coord.


Good luck.

Donna

Correct, but in this case, I'm wondering whether you can set both source 
and target directories to CARET_TUTORIAL_SEPT06/COMPARE_MACAQUE_HUMAN 
and simply use the deform_map in that directory.


This directory contains some, but not all of the source and target files 
cited in the deform_map file.

I have already added the .deform_map file to the directory, which has the
input metric file.
  
This is not normally necessary.  Typically, the file you want to deform 
is in the source directory, while the deform_map you use is in the 
target (atlas) directory.  The output file (usually the same as the 
input file with deformed_ prepended) usually is written to the atlas 
target directory.


But in your case, setting both source and target directories to the 
absolute path of your CARET_TUTORIAL_SEPT06/COMPARE_MACAQUE_HUMAN 
directory may work.  Then you could navigate to your data file as 
needed, and let Caret write your deformed data file to your 
CARET_TUTORIAL_SEPT06/COMPARE_MACAQUE_HUMAN directory.

use them).

When I click the Apply button, I immediately receive the following
error
message:

Deform Error
Is deformation map file valid? You must select a data file for
deformation. You must select the output name for the deformed file.

I tried to apply deformation map from two different .spec files:

1) Macaque F99 atlas directory, which has deformed metric files (from
individual macaque to F99). I added/appended the .deform_map file to
this
.spec file before applying deformation.

2) COMPARE_MACAQUE_HUMAN directory (as a part of CARET_TUTORIAL_SEPT06
directory). I added/appended my metric files to this .spec file before
applying deformation.

In both cases, I got the same error.


Thanks for your helpful comments/suggestions,

Reza

Dear caret-users,

David Van Essen suggested me to use the following .deform_map file for
deformation of macaque F99 to Human PALS:

RegF99toPALS_23-LDMK-VE_Macaque.F99UA1.RIGHT.Register-with-PALS_23-
LDMK-VE.73730.spec.deform_map

  

Once you have a deform_map file, you can use it to register data
sets  from monkey to human WITHOUT re-running a registration.  This
is done using the Surface: Deformation: Apply
