ICA component's correlation to new templates
Dear all,
If I want to computer the ICA component's correlation to other templates (e.g., Yeo's 7 networks), how can we implement the nii/img files of the new networks in Conn?
Thank you very much
Best wishes

RE: ICA component's correlation to new templates
Dear Yiquan,
CONN expects template files defined as a single 4d NIFTI file containing one 3d mask (with 1/0 values) per region/network of interest. For example, for Yeo's 7 network parcellation you may use something like the following in order to create such file:
rex split Yeo2011_7Networks_MNI152_FreeSurferConformed1mm_LiberalMask.nii
spm_file_merge(spm_vol(char(conn_dir('Yeo*.rex.roi.img','-ls'))),'Yeo2011_template.nii');
Hope this helps
