hi XAvier, Thanks for your response. It was a question more of about how you would interpret the negative values(distance) in a particular component.

Then, negative means an opposite direction. Is that >right? g_dist gives the distance and the component in each direction. The components been the difference between the atomic (or COM) positions there is no problem in having a negative value. > > Abu Naser > > School Of Life Sciences > Heriot-Watt University > Edinburgh EH14 4AS > Email: [EMAIL PROTECTED] > Phone: +44(0)1314518265 >Fax : +44(0) 131 451 3009 > > > > > > > -----Original Message----- >From: [EMAIL PROTECTED] on behalf of David van der Spoel > Sent: Tue 25/09/2007 9:42 AM > To: Discussion list for GROMACS users > Subject: Re: [gmx-users] g_dist > > Naser, Md Abu wrote: >> >> >> Hi all user, >> >> I have just calculated a distance between backbone and side chain of the >> same protein.
