<p class=MsoNormal><font size=3 face=SimSun><span style='font-size:12.0pt'>Dear
all,<br>
<br>
I wanted to use DTI-studio for fiber-tracking. All the Rois were generated from
Roi-editor or MRIcro. However, when I loaded the multiple rois in DTI-studio,
it seemed that only the latest loaded ROI had been used for tracking and no roi
operation could be used. Could anyone tell me if there is a way to load two or
more ROIs simultaneously and to do the "and" operation on the ROIs?<br>
<br>
Another question. I have downloaded the .c files of AIR from their website.
However, it failed to be compiled using VC. Could anyone show me which compiler
should I use<span lang=ZH-CN>？</span> Or if anyone want to share his/her .exe
files, I'd be grateful.<br>
<br>
Thanks a lot!<br>
<br>
Maggie <o:p></o:p></span></font></p>
