you want to combine two DTI datasets with different b-table. For example one
30-orientation and one 15-orientation.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>You can load the 30-orientation data and
15-orientation data into one window. First open the 30-orientation using the
"open" icon at the top left menu and then get a new viewing window. Then
open the 15-orientation using another "open" icon at the right column
of the viewing window. In this way, you get all 45 + b0s into one window. Then
you can save all into one file using the "save" icon in the right
column. In this way, you can create a concatenated file in which you have
b0+30DWIs+b0+15DWIs.<o:p></o:p></span></font></p>

order of the stored images.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>I was wondering if you could suggest how to combine different DTI
scans, each with a seperate gradient table, in DTI studio. Basically, I
have two DTI scans and I have two sets of gradient tables for each scan
(gradient table for each scan corrected separately for angulations
and motion correction using the DTI gradient table creator code written by Johnathan
Farrell). Next I want to use these separate gradient tables for each scan for
further analyses. Can this be done using the dpf format?<o:p></o:p></span></font></p>
