dear lammps users,

dear vishnu,

i am unable to read the coordinates file in vmd.the error reads
'unable to load molecule 1'.i dont know wat seems to be the
problem.the dump file is enclosed.thanks in advance

your problem seems to be one of the PEPCAC type.

a) this is a VMD problem and not a LAMMPS problem
b) to get proper help, you need to describe what
   _exact_ steps you did, so that somebody can
   reproduce the error, or see what your problem is.
c) VMD will read this file just file, _if_ you tell
   it that it is a LAMMPS file. since your file name
   provides no indication of what type it is, VMD
   fall back to assuming a .pdb format file, which
   your file definitely isn't, so you get an error.
   this is well documented in the VMD user's guide.
d) the VMD documentation (online and shipped) provides
   detailed instructions on how and where to report problems.

again, there is nothing wrong with the file or VMD.

cheers,

hi
i have a similar problem a week ago, my problem was that i use a old version of VMD, the last version of lammps have some change in the output structure of dump file (i think).

other thing that happen to me is that the matlab program 'readdump_one.m' don't can open a dump file with option -1 (read the last position).

bye.

hi

i have a similar problem a week ago, my problem was that i use a old
version of VMD, the last version of lammps have some change in the
output structure of dump file (i think).

the example data file was produced with an old version of LAMMPS
and thus is compatible to older versions of VMD.

other thing that happen to me is that the matlab program
'readdump_one.m' don't can open a dump file with option -1 (read the
last position).

the e-mail address of the author of those (contributed!) matlab scripts
is given in the README.pdf file. i suggest you contact him.

cheers,
