Dear Bruce,
Now, I change the standard atlas to avg152T1.nii.gz which was included in the FSL and make a mask of superior frontal gyrus (Harvard-Oxford Cortical Structural Atlas). I can map the ROI-mask to the fsaverage surface to create an fsaverage-ROI surface overlay. But when I map one subject thickness data to the fsaverage subject using the following command:
mri_surf2surf --s s12129 --trgsubject fsaverage --hemi lh --sval s12129/surf/rh.thickness --tval ~/Desktop/mask/rh.thickness.fsaverage.mgh --reshape
it said:
Reading source surface reg /Users/wangkangcheng/Desktop/dataplus_60/s12129/surf/lh.sphere.reg Loading source data ERROR: dimension inconsistency in source data Number of surface vertices = 146027 Number of value vertices = 145656
How could solve this problem?
Thank you Wang Kangcheng
