Hi
I intend to perform MRI VBM followed by PLS.
So I would like to input the image files which have already been generated by FSL VBM to PLS.
But I am not sure which files are appropriate....
For example, the GM_mod_merg file? Also, the standard template or the template generated by fsl vbm?
Anyone with this kind of experience?
Thanks a lot!

Hi jieyu chuang
You can use whichever dataset you prefer -
PLS for structural can take as input any segmentation results (e.g., gray-matter probabilities). The only restrictions are that all data are in the same template space, and that you have a mask that defines "brain" as we consider zeros to be true zeros (not background)
so the choice of template is up to you. Any pre-processing (e.g., smoothing) should be done prior to PLS as well.
hope that helps,
nancy
