The following syntactic definition is used in many molecular dynamics
application statements:
trajectory-statement:==
ASCIi=logical
specifies whether
input trajectory file(s) are
ASCII (ASCIi=TRUE) or binary (ASCIi=FALSE).
This statement must be issued before the INPUT files are
specified to enable proper opening of the input files.
(Files are opened in the specified mode as soon as an
INPUt statement is issued.)
BEGIn=integer
specifies the
first frame to be
read, in integration step units. This number can refer
to any frame of the trajectory; i.e., reading can begin
at any place in the trajectory file.
INPUt=filename
specifies the
name(s) of the trajectory file(s); several input files can
be specified and read in the given order.
SKIP=integer
specifies the number of
frames to be skipped between successive readings, in
integration step units. This must be a multiple of
the frequency with which the
trajectory was saved (e.g., NSAVC in Section
11.1.6).
STOP=integer
specifies the
last frame to be read from the
trajectory file, in integration step units. It has
to be equal to or smaller than the total number of integration
steps saved in the trajectory file.
BEGIn, SKIP, and STOP refer to integration step units.
