Hi sd,<div><br></div><div>When we do multi-channel, you submit two different images from the same subject. For example, if you did DTI, you can get b0 image, FA image, MD image, etc. </div><div><br></div><div>If you submit two FA images; one from the atlas and one from your patient data, it is "single-channel" LDDMM.</div>
<div><br></div><div>If you submit FA and b0; FA & b0 from the atlas and FA & b0 from your patient data, it is "multi-channel" LDDMM.</div><div><br></div><div>The multi-channel LDDMM may give you more accurate registration between the atlas and the subject. Both single and multi-channel LDDMM give you only one set of Hmap/Kimap to match the atlas and subject images.</div>
<div><br></div><div>Hope this clarifies your question.</div><div><br></div><div>Susumu<br><br><div class="gmail_quote">2011/12/14 sd <span dir="ltr"><<a href="mailto:sd880131@126.com">sd880131@126.com</a>></span><br>

<div>Dear mristudio users，</div>
<div>Now I'm using the Diffeomap to aline my data,I find that I can only submit 2 subjects for the LDDMM multichannel process.After the successful mssage appeared,I need to rewrite my email and select another 2 data and re-select my template. Is that right?Or just caused by my mistaken operation?In addition,should the 2 subjects I selected from the same sample?This has a ''Hmap'' and a ''Kimap'' in the result.zip I download from ftp,I want to know their meaning respectively.</div>
<div>Thank you for your kindness.</div></div></div><br><br><span title="neteasefooter"><span></span></span><br>_______________________________________________<br>
