The MNI <-> Talairach Tool
This simple tool allows a user to map from MNI to Talairach coordinates and back as well as obtain information about the location of any point in this MNI (Colin) Brain image.
To open the application, go to its web page at https://bioimagesuiteweb.github.io/webapp/mni2tal.html
Figure 1: The MNI2Tal tool.
The controls are as follows:
-
A,B,C — These sliders allow you to set the MNI X,Y and Z coordinates respectively. Alternatively, you may click in the viewer directly to change the cross hairs as in the orthagonal viewer.
-
D — If this is enabled, the Broadman area atlas are overlaid on the anatomy as shown in the smaller view to the right.
-
E — This is the MNI Coordinates control. You may enter the X, Y and Z coordinates directly in the text boxes in this line and either press the enter or the
Gobutton to navigate to this location. -
F — This is the same as E but you enter Talairach Coordinates instead.
-
G — This allows you to select a Brodmann area. The viewer cross hairs will go the centroid of the area.
Any changes to E, F , G or the viewer will update all of these. So any changing in MNI coordinates will result in updated values in (F) and (G).
- H and I — These buttons allow you to load a
.csvfile containing a list of either Talairach or MNI coordinates (one point per line) and perform a batch conversion. A.csvfile will be saved with the result.
Application Info
The MNI to Talairach mapping is from Lacadie et al. NeuroImage 2008. The Brodmann area definitions are from the following abstract: C.M. Lacadie, R. K. Fulbright, J. Arora, R.T.Constable, and X. Papademetris. Brodmann Areas defined in MNI space using a new Tracing Tool in BioImage Suite. Organization for Human Brain Mapping, 2008.
