Hi, Sorry for the confusion. Now I have generated a small xtc file and a very big pdb file. I can able to access small xtc file but unable to read the large pdb file (~10GB) (terminating with the same error as reported earlier). Does it mean my installation has some problem? On Mon, Oct 5, 2015 at

Hi, That unfortunately doesn't tell us anything, since 1.5GB can still be read with 32-bit file operations. You didn't answer any of the questions: can you open very small xtc files, or very large (requiring 64-bit access) gro/pdb files, or not? We are still thinking that you should be able to ope

Hi, Sorry for the delay in reply. I am able to access pdb/gro files of size 1.5 GB with Gromacs-5.1 version. My Desktop is 32-bit whereas my xtc files were generated on our super cluster, which runs on 64-bit O.S. On Fri, Oct 2, 2015 at 9:46 AM, Teemu Murtola wrote: > Hi, > > On Thu, Oct 1, 2015

Are you saying that you cannot open any xtc files? If that is the case, then this may not have anything to do with 64-bit for support. Can your Gromacs compilation open any files? You will need to isolate the problem a bit to help diagnosing it, since we don't have access to your system. Teemu On

This error has nothing to do with the contents of the file, but rather the operating system appears to be telling Gromacs that the file cannot be opened or that it is not a regular file. With the information here, it's difficult to say anything more; if you want to debug this further, the relevant
