Yes, I have managed to see the rois by adjusting the view, but still can't do the back projection. The manual matrix transformation (Hmap->InvertedAIR) gives the result in 181x217x181 instead of my 128x128x66. See attached.<div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Dorian,<div><br></div><div>I think it is just a matter of display intensity. The ROI locations have "1" and non-ROI pixels are "0". So, you have to right click on the image (looks like blank) and adjust the display intensity scale to see the dark ROIs (1 out of 256 grayscale is not visible).</div>
<div><br></div><div>As for the batch processing of TRS to each subject data, we have executable codes. </div><div>Xin and Hangyi, maybe we should post the executables somewhere in <a href="http://www.mristudio.org" target="_blank">www.mristudio.org</a>?</div>
<div><br></div><div>Yajing, how did you apply the TRS to each subject?
