Hi Susumu,<br><br>I am interested in the tensor data (eigen vectors, eigenvalues etc.).<br>I created the raw file, but not sure how to read the matrix data. Is it a Binary file? What is the format like?<br>I will appreciate any help in this direction.<br>
<br>Thanks and regards,<br>Subarna Ghosh.<br><br><div class="gmail_quote">On Tue, Dec 15, 2009 at 4:20 PM, susumu mori <span dir="ltr"><<a href="mailto:susumu@mri.jhu.edu">susumu@mri.jhu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Hi Subarna,<br><br>1) Do you have to use the nrrd format? If you save the matrix as a "raw" file, the tensor elements will be stored as (dxx, dyy, dzz, dxy, dxz, dyz) x D1 x D2 x D3 where D1-3 are the dimensions of the image matrix.<br>
2) Are you asking the exact format of the tensor-nrrd file created by DtiStudio?<br><font color="#888888"><br>Susumu<br><br></font><div class="gmail_quote"><div><div></div><div class="h5">On Sun, Dec 13, 2009 at 11:19 AM, Subarna Ghosh <span dir="ltr"><<a href="mailto:subarna29@gmail.com" target="_blank">subarna29@gmail.com</a>></span> wrote:<br>

Basically i need all the values in the form of matices for some processing and I am not sure how to do it. <br>
I used various examples given : itkNrrdVectorImageReadTest.cxx etc.<br>Please let me know about how I could go about it.<br><br>Thanks !<br><br>Regards,<br><font color="#888888">Subarna Ghosh.<br>
