Dear all,
I have 115 subjects , and I would like to perform average cortical
thickness ,pial surface .
I have used mri_concat for this and i am getting dimension mismatch
*" mri_concat k***/surf/lh.thickness --mean --o
/media/vasudev/vkirsch4/Data_Driven/Thickness_Pial/lh_thickness/lh.thickness.fsaverage.mean.mgh
ninputs = 115Checking inputsERROR: dimension mismatch between
k100/surf/lh.thickness and k102/surf/lh.thickness "*
I have checked the dimensions of the subjects and following is the output ,
it seems there is a problem with dimensions of all the thickness files,
could some one please let me know how i could perform group average
thickness in this case ?
