Thats exactly what i do, i take the image files from dtistudio and load
them in the roi editor. i wanted to upload an anatomical picture to
better draw y rois because i work with rats. is it possible to dothis
even if the matrix and fov are not the same?
thanks

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.

	Hi
	
	I am having problems with DTI studio crashing when trying to
save ROI's. 
	
	This happens after I draw an ROI and click the save button. Then
a dialog (ROI File Format) comes up giving a choice of different
formats. I choose Graphic Compatible (default). After clicking OK, a
crash window comes up a few seconds later. It is labeled MriView3D MFC
application. The only technical information I can find is the following.
	
	AppName: dtistudio-latest-x86.exe     AppVer: 1.0.0.1
ModName: msvcr80.dll
	ModVer: 8.0.50727.4053     Offset: 00014458
	
	This occurs whether I have drawn 1 or more ROIs. (fixed size
ROI, oval).
	The size of the ROI does not matter (4 voxel or 10 voxel)
	It occurs with DTI studio x86 and x64. 
	It occurs with versions 3.0.2 and 2.4.1 of DTIstudio.
	It occurs whether I have a complete dataset loaded 35
directions, or even if I load just 1 image and draw an ROI on it.
	It occurs on an HP core duo 2 system running Windows XP SP3, and
on a redhat linux KVM virtual machine running windows XP x64.
	Reinstalling vcredist_x86 or vcredist_x64 from the DTIstudio
website does not help on any of the systems.
	
	Any suggestions on how to fix?
	
	Darren
