Alejandro-

To answer your first question, you need to explain more about "different
positions". But in case you have multiple structure files (*.dcd or *.pdb)
corresponding to one psf file and want to put them into one, you can use the
"animate write dcd" as follows:

  mol new ${molname}.psf
  mol addfile *.dcd first 0 last -1 step 1 waitfor all
  mol addfile *.pdb
  set nf [molinfo top get numframes]; puts "Number of frames loaded: $nf"
  set sel [atomselect top all]
  animate write dcd ${molname}-out.dcd beg 0 end -1 sel $sel waitfor all top

cheers,
Long
