Re: an error when merge pdb and psf files in vmd for big model

Farzad,

At 2M atoms, this is most likely happening b/c pdb is a column-delimited
format file. The atom index field runs out of columns.

If you are experiencing problems with 2M atom pdb/psf pairs in namd
(but at 2M atoms, you should still be ok ...) then you could use instead
the js file format.
