<div dir="ltr">Open the map file and make sure the "Operation" field under each roi is correct. These are numbers like 0 for OR, 1 for AND, 2 for NOT. Should start always with OR.The easiest way is to edit the map file produced by DTIstudio and point to .dat files created in ROIeditor. It works 100%.<div>

I'm using ROIs for fiber tracking.<br>
<br>
I used ROIeditor to generate binay map files, and changed<br>
ROIMap_map.dat to ROIMap_map.map.<br>
It worked! I can load multiple RoIs at ROIEditor, but I can't figure<br>
out how I could load it on DTI studio.<br>
I tried to load map file using the "load" icon in "Fiber" tab,<br>
"ROI-Operation" section, but nothing happened.<br>
Of course I finished whole brain fiber tracking before I load ROIs.<br>
How could I find fibers connecting ROIs with my map file on DTI studio?<br>
<br>
Thanks,<br>
