**Undefined function or variable 'splitstring'.** and

[TRDim]

Dear Shayo,

I am trying to run the command for freesurfer-Linear :mixed Effect Model. I am trying to upload the qdec.ased.table using ;Matlab as described in the following link:
https://surfer.nmr.mgh.harvard.edu/fswiki/LinearMixedEffectsModels

and I face the following issues :

[tbl, rowid, colid] = fast_ldtable(['./outdir/aseg.long.table']);
Undefined function or variable 'splitstring'.

Do you have any suggestion? Thank you
