Have these been produced by NAMD ? The DCD file format is binary, which
means that (i) normal humans can't edit them with a text editor (but
hexedit would do), (ii) because these are the result of your simulation,
you should analyse them, not 'edit' them. Google for 'molecular dynamics
analysis software'. Most people use programs like VMD and/or the tools
from the gromacs suite.

Too vague. If you already know which programs you'll use for the analysis,
and if these programs can read and process your trajectory files, then you
are set to go. How could anyone tell you how to make an unspecified
fortran code go faster with some unspecified trajectory files (and for
some unspecified analyses) ?
