Hello Atila and Diego,
I think that NetCDF works under linux version of vmd but not under windows. This was the case when I tried to open cdf trajectory. You should reconvert cdf into mdcrd and than open it in windows vmd.

If your trajectory is in .nc there should be no problem with that, vmd recognize automatically the binary file...unless you have a problem with the topology file (e.g. the atom number don´t match!!)

  Dear Diego,

  Thanks for your answer.

  I converted .mdcrd file to .nc file. In VMD, there is amber7 parm in file type section of molecule file browser window. But there is no netcdf in file type section.

  After loading .prmtop as AMBER7 parm, how to load .nc file as netcdf? I load .nc file, but nothing happened.

  I have a general question. Is there all things needed for analysis of trajectory in .nc file?

  After converting .mdcrd files to .nc files, can I deleted .mdcrd files? There is no enough memory in my computer system.

    Just load your .prmtop as AMBER7 parm and the .nc file into the prmtop as NetCDF...that's all!

      Dear vmd users,

      I saw my amber trajectories by loading *.prmtop and *.mdcrd fils.

      Now, I have *.netcdf file instead of *.mdcrd file.

      In this case, how to see my new trajectory using vmd?
