Thanks for your help. I have downloaded Colin 27 subject, and the Surfrend toolbox. But I still have some questions about the process.
1. You said I need transform the Colin 27 to the latest FS version (v.5.2). But i don't know how to do this. It is helpful if you can provide some information.
2. How does the Colin 27 space differs from fsaverage MNI305 space? The group analysis of cortical thickness is conducted in fsaverage space, after importing AAL ROI into Colin 27 space, should i transform the obtained ROI into fsaverage space?
3. i don't understand what is the register.dat between COlin 27 and SPM-s single subject t1.nii used for? I have tried the Surfrend, and found there was no entry for input of register file during the processing.
Best wishes.
Hi,
In my case transformation to fsaverage did not work very well. What I did was:
- from Surfrend page download Colin 27 subject and transform it to the latest version (now 5.2)
- with bbregister obtain register.dat between this Colin 27 subject and SPM-s single subject t1.nii, which is the 2mm version of Colin 27. AAL-s are defined in Colin 27. As they are the same subject, the registering is very good.
- now you can import every AAL ROI (in .nii form) to an annotation or in the form of individual labels to your FS Colin 27, using the newly created registering file.
- now you can use surf2surf or label2label to go to your subjects and obtain stats.
Br!
Hi all;
I need a suface-based aal template which is compatible with FS surface file. Is there a way i can get the surface-based aal template? I have an idea, that is to just transform the AAL template (.nii file) in MNI space onto the surface template (e.g. fsaverage template) in FS. Is it correct? if in this case, how can i do the transformation?
Any suggestions appreciated.
Besh wishes.
