<DIV><FONT face=Arial size=2>Hi Graeme,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I want to follow up Xin's comments. First, please
don't be confused by "binary" and "binary map" formats. The "binary" format
simply saves the ROI as 0/1 maps (default extension is *.dat). The "binary map"
format saves not only the binary ROI files (*.dat files) but also an
additional text file, (*.map file) which you can open and see. To load all
files saved as the "binary map" format to DtiStudio, you have to load it as, of
course, "binary map" format in DtiStudio. Then DtiStudio looks for the ".map"
text file, not the actual 1/0 binary ROI files (*.dat files).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There is one catch, though. When you saved the ROI
files by RoiEditor, you can't specify which ROI is for "AND" and which ROI is
for "OR". There are "AND", "OR", "NOT", and "CUT" operations you can choose to
combine multiple ROIs. Without this information in the *.map text file,
DtiStudio doesn't know what to do.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The best way to learn the syntax of the "*.map"
file is to create this file using DtiStudio and study the inside. You can do
usual fiber tracking by DtiStudio manually. Please make sure that you draw more
than 1 ROI and combine them "AND" or "NOT", as you want. Then try
"save"->"Binary Map" in the ROI operation section. Once you saved your ROIs
using DtiStudio, look for the saved ROI files. You should be able to find a
"*.map" file you just saved. Open the "*.map" file by a texteditor. The file
contains not only information about your ROI data, but also some explanation
about the syntax at the bottom.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Please let me know, if you have any more
questions.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [Mristudio-users] Analyze
ROIs</DIV>
<DIV><BR></DIV>Hello,<BR><BR>I am a new DTIStudio user, and am experiencing
some confusion regarding ROI data formats. I have two issues:<BR><BR>1) I
would like to import ROIs drawn in MRICro (analyze format) into ROIEditor for
statistics calculation, However, it appears that ROIEditor will not read
the analyze files, and gives an roi header file open error. It also refers to
a .roihdr file in the error, rather than a .hdr file. Is there anyway to solve
this issue?<BR><BR>2) I would also like to import ROIs into DTIStudio fiber
tracking, in order to delinate seed and target ROIs for tracking of fibers. I
noticed an earlier mailing list post about using ROIEditor to make these ROIs,
and then save them as binary map files for the fiber tracking ROI module in
dtistudio. I did this, and the file was saved as a .dat file by ROIEditor.
However, then when I went to load the roi in dtistudio's fiber tracking tab in
binary map format, it was asking for a .map file. I forced it to open
the binary map file I had saved in ROIEditor (ending in _map.dat), and while
it appeared to load, it did not appear on the image, nor did any fibers appear
when the 'selected' radio button was highlighted. I feel I must be making some
simple mistake here.<BR><BR>Thanks for any help or advice and for supporting
this mailing list!<BR><BR>Graeme<BR clear=all><BR>-- <BR>Graeme C. Schwindt,
