Would the best solution be to average the frames of the first file or can I specify just one frame?<div>Corinna</div><div><br><br><div class="gmail_quote">On Mon, Jul 11, 2011 at 1:17 PM, Corinna Bauer <span dir="ltr">&lt;<a href="mailto:corinnab83@gmail.com">corinnab83@gmail.com</a>&gt;</span> wrote:<br>

In general, that error means the number of elements in your first input is not equal to the number of element in your second.<br>
<br>
Can you run the command and copy-paste the output into an email? Also, run &#39;mris_calc&#39; with &#39;--verbosity 10&#39;. That will print out additional (useful) information.<br>

When running fscalc, I get the following error on some of my subjects<br>
but not all of them,<br>
<br>
mris_calc:<br>
         Sorry, but I seem to have encountered an error.<br>
         While checking on input filetype sizes,<br>
         I found a size mismatch, i.e. len(input1)!=len(input2)<br>
<br>
Any suggestions?<br>
<br>
Thanks,<br>
Corinna<br>
