Export Code for VTA calculation

[maria]

Hello Lead-DBS team,

I would like to see if it is possible to export the code for VTA calculation. I have tried checking the “Render 3D” and selecting the Export Code button, however I keep getting an error:

Error using ea_export (line 8)
Unable to run the
‘@(hObject,eventdata)lead_dbs(‘exportcode_Callback’,hObject,eventdata,guidata(hObject))’
function because it calls the ‘uiputfile’ function, which is not supported
for this product offering.

Error in ea_run (line 80)
ea_export(options);

Error in lead_dbs>exportcode_Callback (line 1103)
ea_run(‘export’,options);

Error in gui_mainfcn (line 95)
feval(varargin{:});

Error in lead_dbs (line 43)
gui_mainfcn(gui_State, varargin{:});

Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)lead_dbs(‘exportcode_Callback’,hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback.

I am not sure if that can be done in that way, since the VTA simmulations is in another gui button in the 3D render.

Looking at the GitHub repository I found the function ea_genvat_dembek, which requires inputs:
VAT=ea_genvat(coords_mm,stimparams,options).
I assume that each of the inputs correspond to:
– coords_mm = reco.mni.coords_mm (from ea_reconstruction.mat)
– stimparams = S (from stimparameters.mat)
But I am not able to find what “options” refers to, could you let me know where to find it?
In theory, if I generated the two structs needed, and give the options, could I ran the dembek simulation and generate the nifti files with “VAT=ea_genvat(coords_mm,stimparams,options)”, or do I need any other function?

Thank you!

Hi Maria,

yes, the export code.. button doesn’t help you there.
But you’re right that the ea_genvat_*.m files should work.
You can generate an options struct by using

options=ea_getptopts(‘/path/to/your/patient/’);

Best, Andy
