Thanks a lot for your help, actually I do not know the exact file format
at the moment
all what I know is :
"The DCD files (the trajectory files) are single precision binary
FORTRAN files, so are transportable
between computer architectures. They are not, unfortunately,
transportable between big-endian (most workstations) and little endian
(Intel) architectures "

is this enough????

best regards
