REX for CONN data

Hi All -

I am using REX to extract values from my CONN data. One my ROIs that I used in the analysis was taken from the "networks" that come with CONN. When I tried to load "networks" into the REX GUI, MATLAB gives me this error message:

Expected one output from a curly brace or dot indexing expression, but there were 8 results.

Error in rex>rex_image (line 1047)
[gridx,gridy,gridz]=ndgrid(1:a.dim(1),1:a.dim(2),1:a.dim(3));

Error in rex>rex_do (line 596)
[XYZMM{r},XYZWW{r},XYZNN{r},XYZnames{r},ROIA{r},ROIB{r}]=rex_image(roi_path,params.level,'image',params.select_clusters,params.selected_clusters,params.mindist,params.maxpeak,params.dims(min(r,length(params.dims))),params.roi_threshold);

Error in rex>rex_gui (line 475)
[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,~data.params.gui||(isfield(data.params,'steps')&&any(strcmp(data.params.steps,'nodisplay'))));

Error while evaluating UIControl Callback.

Can you please help?

Thanks,
