I've tried sending a couple of e-mails to the DtiStudio support staff, but they
have yet to get back to me. While waiting for their reply, I was wondering if
anyone in this newsletter would be able to answer my questions. Below, I have
copy-pasted both my e-mails. I apologize for the length, I got a little carried
away in my curiosity. <br>
<br>
If anyone can help, it would be greatly appreciated.<br>

<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Dear
Support Team,<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>I am writing
you in reference to your program DTI Studio. Let me begin by stating that I am
very new to diffusion tensor imaging, and am trying to use your program as a
stepping stone into that field of study. For the record, I am a research
assistant in a lab that is registered on your website (<a
href="http://dtistudio.org/" target="_blank">dtistudio.org</a>) under the
username slee56. <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>I write
to you with only a few hours of experience with the program under my belt. The
manual which you posted alongside the software is helpful in knowing how to
open files and view them. For the purposes of learning how the program works, I
downloaded the data set <a
href="https://www.mristudio.org/download/data/dti/01/020729/DTI/31/01_020729_31.rec"
target="_blank"><font color=black><span style='color:windowtext;text-decoration:
none'>01_020729_31.rec</span></font></a>. Initially, I was able to boot up the
program and load the data set via file -> dtimapping. Using the gradient
posted next to the data set on your demo data database, and leaving all other
settings as they were, I was able to bring up the axial, sagittal, coronal, and
3-d views of the .rec file. Next, under the dtimap tab, I clicked "tensor,
color map, etc." to come up with the different maps. Once this was
completed, I was able to view the different maps, but this is where my problems
began. <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>As I
stated earlier, I am very new to this field, and thus am at a loss when it
comes to actually <b><span style='font-weight:bold'>interpreting the data</span></b>.
<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>For this
reason, I am contacting you to ask whether you have some documentation on how
to "read" all the various DTI maps that this program is capable of
creating, along with a glossary which explains every term used in the program.
For me to create maps and not know what I am looking at presents a problem
that, hopefully, you can help me with. I have looked through the user manual
that is on your webpage, and while it is very helpful in utilizing the program
itself, it does not help me interpret the images. For example, I am completely
unaware how to find within what area of the brain the diffusion is higher or
lower than normal, or even know what normal is for that matter. <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Finally,
I was wondering if you could tell me that after creating the "tensor,
color maps etc," where I can view the data this calculates, and what those
figures mean. <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Also,
just as a side note, under the dtimap whenever I click any of the buttons under
"calculation," 40% of the time it causes the program to severely
stall and/or crash altogether.<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>I really
appreciate your help in this matter, and hope to soon become knowledgeable in
this area with your aid. So if there is some documentation explaining every
single in and out of what DTI images are, show, and help with, it would be
incredibly useful to me. <o:p></o:p></span></font></p>
