Subject: Re: [Freesurfer] problem of group analysis

It's having problems reading the 2nd column of the 1st row (ie, [1][2]]). Does your age.mat file have commas in it? If so remove them and try again.

Hello, Group

I have a question about mri_glmfit. I can not run this commend on my data.

An error

"MatrixReadTxT: could not scan value [1] [2]

file exists

ERROR: loading C age.mat" 

appeared. 

I do not know what is wrong. 

The only warning I saw is "ERROR: cound not find volume $SUBJECTS_DIR/average/surf/../mri/orig. Does it exist?" when I ran mri_surf2surf.  

 

I am doing group comparison of cortical thickness on 2X2 data. The following is my fsgd.txt

 and *.mat.

 

GroupDescriptorFile 1

Title thick vs group

Class group1

Class group2

Variables age

Input APL02R700 group1 48

Input APN02G650 group1 35

Input APN02G700 group2 35

Input APN03L700 group2 30

DefaultVariable age

age.mat: -1, 1, 0

If anyone know what is wrong in my analysis, please help.

Thank you in advance,

 

Xin
