Hi Maggie,



Please try the “Binary Map” option. The best way to learn this format is
to save ROIs by DtiStudio and study the saved files.



Please do the following;



1)       Using DtiStudio, draw one ROI as “OR”, second ROI as “AND”, and
third ROI as “NOT”.

2)       Save the ROI. In the ROI section, there is the “save” icon. After
clicking it, a new dialog window appears. Here, choose the “binary map”
format.

3)       Assign a file name and save it.

4)       Go to the directory where you saved the ROI files. You should find
4 new files. Three large files to save the ROI locations by 1/0 binary
information. This file has the same 3D dimension as the images. The fourth
file is a text file, which you can open and read inside.

5)       At the bottom of the text file (the fourth file), there is a
description about the syntax. The file is self-explanatory. Once you
understand the content, it is very easy to modify this file to load ROI
files you created by RoiEditor and other software.



Please let us know if you have any problem with this approach.

Dear all,

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?

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？ Or if anyone want to share his/her .exe files, I'd
be grateful.

Thanks a lot!

Maggie
