Hello Freesurfer Experts,
I am performing a mass-univariate analyses using the LME toolbox for longitudinal studies.
After running both mris_preproc and mri_surf2surf , I load the lh.thickness_sm10.mgh file using
[Y,mri] = fs_read_Y('lh.thickness_sm10.mgh');
Next, I run the following command:
Qdec = fReadQdec('qdec.table.dat');
However, it seems that the output is entirely in string format "166 x 1 cell". The first row reads as "'fsid fsid-base years group gender age'" in a single column.
Because of this, I am running into problems when I try to execute the following steps:
Qdec = rmQdecCol(Qdec,1); (removes first column)
sID = Qdec(2:end,1); (grabs the subjects' IDs)
Qdec = rmQdecCol(Qdec,1); (removes the subjects'ID column)
M = Qdec2num(Qdec); (converts to a numeric matrix)
[M,Y,ni] = sortData(M,1,Y,sID); (sorts the data)
Your help will be greatly appreciated!
Many thanks.
Best Regards,
Elijah
