<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">If you are reading Analyze data, I believe
all the info about data dimensions is read from the hdr file. The boxes for
image dimensions and pixel sizes are deactivated. It may show some numbers but
they are not meaningful and you can't change them. Only after you choose the "analyze"
format and data are read, correct dimension info is loaded from the hdr file.</span></font></p>

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Now, it is possible that the data input
window still remembers old invalid numbers, which interferes with the data
loading. Please try following;</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">1) First choose the "raw" format
and activate image dimensions and fov windows. </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">2) Type in some meaningful numbers. This
will erase prohibited numbers such as minus values remain in the windows.</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">3) Then switch to the "analyze"
format. All "voxel size" windows should be deactivated</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">4) Click OK.</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">I hope it will work.</span></font></p>

<br>
Thanks very much. Unfortunately, when I downloaded this new file and
changed the extension, I still get the same problem. I attached a
screenshot if that helps. I think the problem may be that the program is
storing information from the previously opened files somewhere on my hard drive
and then using those values each time. I think this because when I
downloaded your new program and went to the file menu, there were some
previously opened files there. It did this even when I deleted the program
and re-downloaded it. Do you think this could be fooling the program into
thinking that the voxel dimensions were the same as the previous image?
Where would this be stored so I could delete it and try again?<br>
<br>
Thanks again very much for your help,<br>
Jason</div></div></span></font></p><div><div></div><div class="Wj3C7c">

<br>
seems that your version has a bug. :))<br>
<br>
you can got the latest version in our website. for your convenience, I attached
the program as a ".data" file. please rename it back to
"DtiStudio.exe" before you can play with it in you PC.<br>
<br>
let me know if you have more questions.<br>
<br>
regards,<br>

Hello,<br>
<br>
I am new to DTIstudio so I apologize if this question is too basic.<br>
<br>
I am trying to load an Analyze image into DTIstudio. When I click on any<br>
image to open it, the image parameters screen comes up in the DTI studio<br>
window. There, I make sure that Analyze radio button is selected.
The<br>
pixel dimensions are set to Pixel size - Width: -0.9375 and Height: 0.9000.<br>
When I click OK, I get the error that "Please enter a number between 0 and<br>
4096". I think this might be because the pixel dimension is set to
be a<br>
negative number? However, I am unable to change the values in the boxes.<br>
<br>
Also, if I try opening up an image with different voxel sizes, the same<br>
pixel size and width are shown in the box. These are incorrect, and I'm
not<br>
sure why they do not change when I open a new image. Also, why can I not<br>
change it manually? Any image I load brings the same pixel width and<br>
height.<br>
<br>
Thanks in advance for any help,<br>
Jason</span></font></p>
