Hi,<br>
<br>
nhis in SIZE is the number of points, per processor, that can be read in.<br>
So, you will want to be sure that the total number of points in <a href="http://hpts.in/" target="_blank">hpts.in</a> =<br>
nhis*np.<br>
<br>
If this is the case and you are still getting strange values in hpts.out,<br>
we can look at other possible problems.<br>
<br>
Thanks<br>
Katie<br>
