Hi Doug,<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Thanks for the reply. I tried mri_concat as you suggested,&nbsp; and got the following: <br><br>WARNING: analyzeRead(): matfile &lt;usual path to&gt;spmfile1-0003.mat exists but could not read ... <br>&nbsp; may not be matlab4 mat file ... proceeding without it.<br>
-----------------------------------------------------------------<br>INFO: could not find &lt;usual path to&gt;spmfile1-0003.mat file for direction cosine info.<br>INFO: use Analyze 7.5 hdr-&gt;hist.orient value: 0, transverse unflipped (default).<br>
INFO: if not valid, please provide the information in &lt;usual path to&gt;spmfile1-0003.mat file<br>-----------------------------------------------------------------<br><br>These files are the outputs from spm_reslice command, and i looked at the contents of the <br>
mat files: they have 2 entries: &quot;M&quot; and &quot;mat&quot;, and store the same matrix. Do you think<br>mri_concat may be getting confused by 2 entries in the mat file? Is there any flag i can<br>use (eg --it analyze ) to make it run?<br>
I would also be interested in using the mri_convert option as an alternative. can you (or anyone)<br>help me with the command line flags?<br><br>regards,<br>sid.<br><br><br><div class="gmail_quote">On Mon, Dec 15, 2008 at 12:11 PM, Doug Greve <span dir="ltr">&lt;<a href="mailto:greve@nmr.mgh.harvard.edu">greve@nmr.mgh.harvard.edu</a>&gt;</span> wrote:<br>

There are two things you can do,<br>
<br>
mri_concat spm_*.img --o 4d.img<br>
<br>
you can also&nbsp; do it with mri_convert, but I don&#39;t think&nbsp; it buys you
anything over using mri_concat.<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; is it possible to combine, using mri_convert, a set
of <br>
3D spm/analyze files into a 4D analyze file&nbsp; ? can anyone help<br>
me out with the syntax, if possible?<br>
