<font face="Courier New" size=2 color=#000000>Hello,</font><br>
<br>
<font face="Courier New" size=2 color=#000000>Since my last inquiry seemed to have escaped notice, I write you again </font><br>
<font face="Courier New" size=2 color=#000000>in the hopes of finding a solution to my problem. </font><br>
<font face="Courier New" size=2 color=#000000>As I wrote in my last email, I’m analyzing the FA values of the optic </font><br>
<font face="Courier New" size=2 color=#000000>radiations and have, so far, extracted them by using </font><br>
<font face="Courier New" size=2 color=#000000>anatomical landmarks and the DTIStudio functions AND, OR and NOT. The </font><br>
<font face="Courier New" size=2 color=#000000>focus of my research concerns the posterior parts of the optic </font><br>
<font face="Courier New" size=2 color=#000000>radiations ending in the primary visual cortex, but I find myself </font><br>
<font face="Courier New" size=2 color=#000000>unable to extract them properly. Using the ROI-Operations in the Fiber </font><br>
<font face="Courier New" size=2 color=#000000>Tab during Fiber Tracking oftentimes results in the removal of entire </font><br>
<font face="Courier New" size=2 color=#000000>fiber tracts instead of just the anterior parts and any attempts to </font><br>
<font face="Courier New" size=2 color=#000000>work with ROI Editor have not been successful so far. </font><br>
<font face="Courier New" size=2 color=#000000>I have seen at least one paper in which the anterior/posterior parts </font><br>
<font face="Courier New" size=2 color=#000000>and their FA values were examined via DTIStudio, so I know it’s </font><br>
<font face="Courier New" size=2 color=#000000>possible, but I’m completely puzzled as how to actually do it. </font><br>
<font face="Courier New" size=2 color=#000000>I would appreciate it *very* much if you could point me in the right </font><br>
<font face="Courier New" size=2 color=#000000>direction. </font><br>
<font face="Courier New" size=2 color=#000000>Thank you for your time. </font><br>
<br>
<font face="Courier New" size=2>Cheers,</font><br>
