hello all，<br clear="all">when
i&nbsp; use &quot;fslmerge&quot; &amp; &quot;3d to 4d&quot; tool in spm5 to merge a group of&nbsp;
.hdr/.img file into a 4D file(.nii and .nii.gz) separately. i find that
the image result showed in &ldquo;fslview&rdquo; is really different.<br>
then i find before merging into 4D file, just use &ldquo;fslview&rdquo; and spm5&#39;s
&ldquo;display&rdquo; tool to check the same .hdr/.img file, the result is also
different. the .hdr/img images showed in &quot;fslview&quot; are grey while
showed in spm5 are more normal as we see usually.<br>
<br>any body have these experience? can you tell me why?<br clear="all"><br>-- <br>Best regards!<br><br>Sen-Hua Zhu<br>Department of Psychology<br>Sun Yat-sen University <br>135 Xingang West Road, Haizhu District, Guangzhou (510275), P.R.China <br>
