I had luck using textscantool with the 1D row cell array but have ran into a snag attempting to use 2D cell array on the same data. This is the error I have picked up:
??? Subscripted assignment dimension mismatch.
Error in ==> textscantool>importDataCallBack at 852
data(2:end,k)=dataCell{k}; %.. just copy in
??? Error while evaluating uicontrol Callback
Let me know if you need more information to debug this.
