Hi Naama,<br>
<br>
I don't think you can directly import Analyze ROI to DtiStudio.<br>
However, Analyze consists of *.hdr and *.img. The *.img file is a raw data.<br>
If the *.img is a binary data, I believe that you can load it as an ROI<br>
through the ROI/ "raw" format.<br>
<br>
One thing you have to know is that the default Analyze format follows<br>
Neurology convention. Because DtiStudio follows Radiology convention, reaing<br>
the *.img directly as a raw data may lead to upside-down location.<br>
<br>
I would recommend you to read your Analyze ROI file as Analyze image by<br>
DtiStudio or RoiEditor first (maybe RoiEditor is better). Then save the data<br>
as binary raw data or "binary map" format. I believe the "binary map" format<br>
is one of the most powerful format to communicate with DtiStudio fiber<br>
tracking function.<br>
<br>
The easiest way to learn the "binary map" format is to draw ROIs for fiber<br>
tracking in DtiStudio and save the ROI as the "binary map" format. You will<br>
find binary ROI files and one text file, which is a kind of a header file.<br>
You can open and read the text file to understand the file format.<br>
<br>
Please let us know if you can follow my suggestion.<br>

Subject: [Mristudio-users] Importing analyze format ROIs to dtistudio<br>
<br>
<br>
This was brought up in the past but I cannot find a clear answer in<br>
the archives - Is there an easy way to import analyze format ROIs into<br>
dtistudio?<br>
<br>
Thanks,<br>
