[Mristudio-users] crash when saving ROI's

[Seongjin]

Darren,

I experienced the similar problem. I wanted to use ROI drawn in ROI panel
but it did not work at all. ROI saving and loading functions seem to work in
FIBER panel, but not in the ROI panel.

If you want to use ROI for DTI metrics such as FA or ADC measurements, I
recommend ROIeditor (a companion tool to DTIstudio). That is more powerful.

I always process data in DTI studio. Then load all the processed data into
ROI editor.
Finally, do the measurement with ROI editor.

The saved ROIs can be reused in the DTI studio for fiber tracking. However,
again, the ROIs could not be used in ROI panel of the DTI studio on my
computers (home computer, laptop, and office computer).

I hope this experience might be a bit of help for your problem in using DTI
studio.
