Use fslroi <diffusionwithtrace>
<diffusion> 0 <nvols-1>
The trace image doesn't
have a bvecs or bvals entry associated with it
does
it?
Peace,
Matt.

[FSL] Problem with Philips TRACE Images in DTI
calculationSábado,
19 de Março de 2011 21:00
Dear
friends,
Good evening,
I have some data made with the
Achieva 1,5 T that produced just one DICOM
Enhanced file.
In
this file I have the B0 the different gradients and the trace file at
the
end.
The problem ins that I can't take off these trace
images for the DTI
calculation.
I tryed to subtract the last
volume using fslplit and then mfslmerge, but
FDT coulnd't compute
the file because a problem in the bvecs and/or bval
files.
I
tryed to edit these files manually, but the program crashes using
them.
I don't know how to ignore the last volume to compute the
DTI.
I tryed with MRISTUDIO, but no success too.
Is there a way
to the program ignore the last volume?
Or can I rebuild the
gradient information (bvec and bval) after I subtract
the last
volume?
Thank you very much.
Lucas
Lessa.
