VMD does not care where information is coming from, so as long
as there is a reader plugin, it can use the information for
visualization and analysis. VMD can read .xtc, .trr, .gro, .pdb,
.g96 files but not .tpr or .top files. there was a converter for
preprocessed topologies to .psf(?) somewhere in the script library.

i don't know, what you understand as "standard analysis" (everybody
will define this differently). reading from the command line works
like with other file types. without a flag VMD tries to guess the
fromat from the filename other than that you can provide the
file type with a flag, .e.g -trr for .trr files -pdb for .pdb and
so on. this is all explained in detail in the VMD user's guide.
i suggest you have a look at that and at the VMD plugin documentation
(both available on-line on the VMD home page) to see if VMD fits
your bill.
