[gmx-users] What method (algorimth) is used to calculate volume of a protein?
Hi everybody, I used "g_sas" command in Gromacs4.0.3 to calculate volume of a protein. I read Gromacs4_manual and found information on internet to understand method(algorithm) used in Gromacs to calculate volume of a protein (or a system consisting of water and protein). But I can not find the solution. I think the method bases on Voronoi construction, but I am not sure. Can you tell me what method(algorithm) is used in Gromacs4 to calculate the volumes. Thank you in advance.

[gmx-users] Making sure I understand an error
Hi, I have a 72-lipid DPPC (MARTINI) system that I ran for 400ns in GROMACS 3.3.3.

[gmx-users] Artificial Shear Flow and Inconsistent Shift Error
Hi All, 1. Artificial Shear Flow: I am trying to do translocation studies and wanted to generate a shear flow without actual water atoms. I checked the mail list and it was mentioned that there is no velocity profile but an option to accelerate the atoms in a group. But I wanted to get the shear flow or the velocity profile without atoms. To make myself clear: I want the boat to navigate through water, with the flow of water but there is no water, am I making sense? So I want an artificial force applied constantly in the channel not on the particle so basically I define the velocity profile using the artificial force. 2. Inconsistent Shifts Error: I received this error in my simulation studies when I used PBC =xyz " There were XXX inconsistent shifts. Check your topology ", checked the mail-list and found the option of pbc = full should be used, but seems it is not available anymore in gromacs 4.0.3, My system is very small around 1000 atoms, and it works fine without periodic conditions, but when pbc is added it runs for some time and then gives me the error. What does this error actually mean? How can I resolve this?

[gmx-users] SD temperature coupling groups
Hi GROMACS user group! Maybe this should be aimed at the developers' mailing list... Anyway, I've been having some problems (blowing up) when I tried to simulate a molecule such that one part is coupled to a thermal bath using SD, and another part is not coupled to any bath. Effectively, the uncoupled part has infinite "relaxation time" (tau-T) which is the same as zero coupling (gamma); however, in the *.mdp file it is unrealistic to put in the value infinity for the tau-T parameter. The 4.0 manual specifically says, in section 7.3.14, "Temperature coupling": tau t: [ps] time constant for coupling (one for each group in tc grps), 0 means no temperature coupling However, when I tried putting in zero I got the following (debugging information log-file) line 267: SD const tc-grp 0: b nan c inf d -inf line 268: SD const tc-grp 1: b 2.08438e-14 c 8.33021e-11 d -2.5e-07 where group 0 had tau-T[0] = 0 and group 1 had tau-T[0] = 1 ps . This shows that when I put zero in the temperature coupling timescale (for SD this is not exactly a first-order relaxation time), the SD parameters blow up. Note that when I put tau-T[0] = 1000 or tau-T[0] = 1, the simulation ran properly. Where in the code can I check that what is written in the manual is, indeed correct? (i.e., I expect an if statement saying that if the tau-T value of some temperature coupling group is zero, then take the inverse of that to be effectively zero).

Is there no solution for this. Is it something to do with speed of the system? I ran the program on HP dual core system. Hi, there were a few issues in do_dssp which I fixed recently. Could you try the most recent version from the git repository, maybe on a short trajectory first?
