Dear all,

The following error pops up after extracting ROI estimates with REX in both SPM8 and SPM12:

Reference to non-existent field 'output_folder'.

Error in rex>rex_do (line 762)
name_dat=fullfile(params.output_folder,[ROInames{rr},'.rex.data.txt']);
Error in rex>rex_gui (line 442)
[data.params.ROIdata,data.params.ROInames,data.params.ROIinfo.basis,data.params.ROIinfo.voxels,data.params.ROIinfo.files,data.params.ROIinfo.select,data.params.ROIinfo.trans]=rex_do(data,~dat
Error while evaluating uicontrol Callback

I assume it is a problem with finding the path to the output folder, but I cannot identify how does REX obtain that information.

Any help will be greatly appreciated.

All the best,
Macià
