Re: Fw: [gmx-users] water molecule can not be settled
I thought the sole purpose of open source discussions and sharing is to help any scientific (or other) community to grow and benefit from each other, without taking into account the Nationality of the beneficiaries. If someone is willingly helping out somebody, whether Indian or not, in the GROMACS forum, then it should not bother Mr. Luis Felipe Pineda de Castro, since to the best of my knowledge it is not affecting him. I would request the moderators of this forum to take adequate measures about such postings as Mr. Castro's.

Re: Fw: [gmx-users] water molecule can not be settled
As I visualized the system, I see a water molecule somewhere between lipid chains near the protein entrance. This has been happen during NPT. I' d like to delete this molecule but with such a kind of fatal error this would impossible. So what's the way? Is there any tricky way to change coordinate of molecule? but I seems also impossible becasue PME problem! So whats the solution?
