Re: [Freesurfer] AD cortical thickness signature

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 ..

[Freesurfer] AD cortical thickness signature

2017-08-15 Thread Yi, Hyon-Ah 
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

Dear FS experts, 

TESTTEST_age_only.fsgd
Description: Binary data
I met an error when I try to run mris_preproc. Actually i succeeded this command with my own scripts and fsgd files before. There are 2groups with one covariates but I keep getting this error like below. mris_preproc --fsgd TESTTEST_age_only.fsgd --hemi lh --meas thickness --target fsaverage --fwhm fwhm10 --o lh.thickness_age.s10.mghERROR: no subjects specified
I attached my fsgd file. 
This fsgd file was made using emacs. Regards, Hyon-Ah Yi. ___
