This should be right, hence my confusion about the histogram. Are you sure<br>
there's only one peak? Have you looked at it with a text editor? There should<br>
be multiple entries in the file, one for each window that you're simulating?<br>

</blockquote></div><br></div>I have included in my simulation some windows past the ~2nm distance between the two groups. The same result occurred, but with a longer separation, the graphic seems to continue rising and the histogram looks even taller. Here are the links for the profile.xvg, histogram.xvg and the rapidshare link for my histogram.xvg file in case you want to have a look. <br>

histogram text file > "<a href="http://rapidshare.com/files/286236452/histo.xvg.html">http://rapidshare.com/files/286236452/histo.xvg.html</a>"<br>The histogram file looks like a diagonal matrix of 200X20, in which the "diagonal" range is of approximately 10 lines, i.e., the first collumn has 10 lines of non-zero entries and then 190 of zeros, the second collumn has 12 lines of non-zeros, the third has the first three lines of zero entries and then 10 or 12 lines of non-zeros and then lots of zeros again, and so on and so forth.<br>
In case you prefer another way for me to show you the histogram text file, please let me know.<br>Thank you<br>
