[Homer-users] Short Separation Proc GUI

[Borbala Kollod]

Hello,
I had similar problems. The very first error is referring to a function
which finds corresponding short-sep channel for every channel. In our
design 2 sources end 8 dets are present of which 2 are forming the
short-sep channels for the sources. Threshold values were separated by
dot.

the error message is:
??? Index exceeds matrix dimensions.

    rho = sum((ones(length(lstSS),1)*posM(iML,:) -
posM(lstSS,:)).^2,2).^0.5;

        eval( fcall );

Thanks for any ideas!

Hello everyone,

I am wondering if anyone has had success using the short separation
channels as regressors, as David showed us in the tutorial on Monday. I
have added the field 'Block_Avg_Short_Sep' to my processing stream but
whenever I edit the value for 'rhoSD_ssThresh' I get an error (error
text
below). When I try to run the processing stream, it gets stuck at the
last
step.

Error:

Attempt to reference field of non-structure array.

Error in EasyNIRS_ProcessOpt>edit_Callback (line 196)
if hmr.copyOptions

Error in gui_mainfcn (line 96)
        feval(varargin{:});

Error in EasyNIRS_ProcessOpt (line 42)
    gui_mainfcn(gui_State, varargin{:});

Error in
EasyNIRS_ProcessOpt>EasyNIRS_ProcessOpt_OpeningFcn/@(hObject,eventdata)EasyNIRS_ProcessOpt('edit_Callback',hObject,[7,4],guidata(hObject))

Error while evaluating uicontrol Callback


Does this mean that our probe array is not recognized as having any
short
separation channels? (We have two source-detector pairs separated by
2.5cm.)

I am using the developer's version of Homer2. I'd be very grateful if
anyone knows the steps to use short separation correctly!

Thank you,

Amanda
