MNI template version

Hi,


I was wondering if there are more details on the exact version of what the ICBM152 template is? For example, is it the ICBM 2009b nonlinear asymmetric MNI template?


Thank you

By choosing "Show Header" from the "Options" pull down menu, you can see in the "Description" of the "Optional" tab that the sould of the image is:

The image has been cropped and resliced to be 256 voxels in the longest direction.

RE: MNI template version

Sorry for my poor phrasing and sorry if I am misunderstanding your response.


Here is my re-phrased question: is the "mni152" template found within MRIcroGL (by going to File > Open Standard > mni152) the same as the ICBM 2009b nonlinear asymmetric MNI template?


I was also unable to find the options you described (see screenshot):

RE: MNI template version

Your screenshot shows the File menu from the Main menu. The main menu provides settings that influence ALL images. Note that MRIcroGL can load multiple images simultaneously that can each have different properties. Therefore, to find details regarding a specific image you must select it in the "Layers" panel and choose image specific options from the "Options" drop down menu in the Layers panel. Note that this drop down menu has an option named "Show header". The image is visibly Asymmetric. 


 


Since the header does not report if it is 2009a, 2009b or 2009c I would assume it is the original (2009a) version before the revisions were added, but you can test this assumption yourself:

RE: MNI template version

Thank you for that information! 

I downloaded 2009a, 2009b, and 2009c from the website then pulled up all 3 in MRIcroGL. However, they all look the same to each other and 'mni152.' Is this the best way to verify which version 'mni152' is, or do you suggest other steps I should take?

Sorry, I would think visual inspection you applied would be the best method.
