<div dir="ltr"><div><div>Hello experts,<br><br></div>I was trying to do connectivity-based segmentation using camino, but I couldn't obtain the atlas_mask.nii.gz properly. When I tried to view the image in mricron, it said the atlas_mask.img file was smaller than described in header. This is what I have done:<br>
</div>1. My atlas which contain label information was obtained by using wfu_pickatlas TD_label.nii. The file was registered to nodif_brain.nii.gz by using fsl flirt. Then I used code below to obtain an atlas_mask.nii.gz file.<br>
<div><br><code>>> fid = fopen('/scans/atlas_subject.img', 'r');</code><br><code>>> atlas = fread(fid, 'int');</code><br><code>>> fclose(fid);</code><br><code>>> mask = atlas ./ atlas;</code><br>
<code>>> fid = fopen('/scans/atlas_mask.img', 'w', 'b');</code><br><code>>> fwrite(fid, mask, 'int16');</code><br><code>>> fclose(fid);</code><br><br></div><div>Then <code>run command (I used the voxeldims and datadims of our data)<br>
analyzeheader -voxeldims 1.7 1.7 2.3 -datadims 128 128 60 -datatype short > scans/atlas_mask.hdr</code> <br><br><br>
</div><div></div><div>But I was confused that what's the atlas_subject.img since the tutorial mentioned both of them.<br><br></div><div>2. When doing fiber tracking, if camino was using a probabilistic algorithm just like fsl, or using a multifiber tracking algorithm?<br>
