Dear FS experts
I’m wondering whether there are ways of getting the single value of ROIs.
I mean to get the value of cortical thickness of AD signature areas, such as supra marginal gyrus, inferior frontal cortex.. and so on .. the values of some areas can be get using aparcstats2table (in the Desikan atlas) as single value however, in the case of frontal cortex, there is no single value for it.
can I get the single value from just averaging of two cortical area ? or are there another way ?
Regards,
Hyon-Ah
HI Hyon-Ah
if your question is how to you compute the mean thickness for an ROI, if you have it in .label format you can simply call
mris_anatomical_stats -l <roi file name> <subject id> <hemi>

not that I know of. You can merge the desired labels into one (mri_merge_labels) and then compute the mean in the merged label

Dear Doug ,,
thanks for your suggestion ..
I have more questions.
1. If then, I can get merged label using mir_mergelabels, As it is ' . label file', so I should run mris_label2annot and mis_anatomical_stats ? 2. is it possible to get the merged value of rh & lh ?
Regards,
Hyon-Ah ..
