<DIV><FONT face=Arial>Dear Susumu, dear all,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I have two questions when using the DTIstudio for DTI
mapping as bellow.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Q1.I'm doing some DKI experiments which have 4 b-value
(500,1000,1500,2000) and 30 directions for each b-value on a Bruker 7T scanner.
I tried to define the multiple b-value gradient table (which was editted from
the 30-direction DTI gradient table I used to define and opened the dataset
successfully) for screening the DWI images for further calculation. But every
time it kept saying that "file size is bigger than DW-image size" and failed to
open the dataset correctly. I wonder if there is any mistake in my gradient
table? Here it is (5 b0 images)....</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Furthermore, what should I put in the "b-value"
option in this multiple b-value case? Would it affect the tensor
calculation?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>

<DIV><FONT face=Arial>Q2. I'd like to save the post-cross-out raw images
(Philips REC file format) in order to record the images I used to calculate the
tensor, but I found no way to achieve that either by using "save" or "save as"
function in DTIstudio. Is DTIstudio capable to save these data? I just want to
achieve that every time when I open the same dataset, it will automatically
show me where I've crossed out for tensor calculation last time. </FONT></DIV>
