Sorry, I attached the wrong file . Here's the average file generate from one of the files I sent in my last mail. I used the command g_analyze -f hbond_115-water.xvg -av hbond_115-water-avg.xvg. Here's the file obtained from this command :-

Hi, I tried g_select to dump the structure with the interacting water molecules, but I don't know know how to do that. I searched for some threads in the discussion but wasn't able to find anything related to my need. Can you explain how can I do that ? On Tue, Nov 12, 2013 at 7:39 AM, bharat

Thanks justin for your replies. I understood the g_analyze related data. I tired g_analyze to dump the structures as you said. But, I didn't find any switch that can be used to dump the structure in pdb format. On Tue, Nov 12, 2013 at 10:15 PM, Justin Lemkul jalem...@vt.edu wrote: On

In addition to my previous question, I have another question about g_analyze. When I used the hbond.xvg file to get the average and plotted the average.xvg file I found that the average value is round 4 to 5 according to the graph. But g_analyze in its final calculation gives 7.150 as the average

I checked the file hbnum.xvg file and it contains three columns - time, hbonds, hbonds that donot follow the angle criteria. In that case SS1 is the average of actual hbonds (2nd column ) and SS2 is the average of 3rd column. Am I right here or not ?? I tried to calculate the h-bond for residues

Thanks for your reply. I was missing the scientific notation part. Now everything is fine. Regarding trjorder, it doesn't measure h-bonds but gives the water nearest to protein. On Mon, Nov 11, 2013 at 10:12 AM, Justin Lemkul jalem...@vt.edu wrote: On 11/10/13 7:18 PM, bharat gupta wrote:
