[Marsbar-users] error with maroi

[<tob...@me...>]

Dear marsbar users,

I tried to run a script in order to extract beta values and received the
following error message:

---------------------------------------
??? Undefined function or method 'maroi' for input arguments of type 'char'.

Error in ==> beta_script at 23
roi_array{1} = maroi(Kug_ROI_1);
----------------------------------------------

Can anybody give me a clue how to fix this?

Below you find the whole script.

Thanks in advance.

Regards, Tobias
