.TH reformat
.SH NAME 
.B reformat - convert trajectory files between different formats
.SH SYNOPSIS 
.B reformat
.I inpfile
.I outfile
.SH DESCRIPTION
Convert a Lagranto trajectory file 
.I inpfile
from one format to another format; the new file is written to 
.I outfile. 
The formats are specified with an appendix to the filename, e.g. "trajectory.1" specifies format 1. If no appendix is given, format 1 is chosen.
.SH PARAMETERS
.TP 15
.I inpfile
input trajectory file
.TP 15
.I outfile
output trajectory file (can be the same as inpfile).
.SH FORMATS
Formats must be specified with an appendix to the filename. If no appendix is given, format 1 is chosen.
.TP 5
.B .1
ASCII file; the trajectories are sorted according to their starting positions. Different trajectories are separated by a blank line. This format is the only one supported
by the Matlab and NCL visualisation scripts (see
.B lagrantohelp/visualisation).
.TP 5
.B .2
ASCII file; the trajectories are sorted according to their times. Different times are separated with a blank line.
.TP 5
.B .3 
unformatted Fortran; this is the most efficient format, but least portable one.
.TP 5
.B .4 
netCDF; portable and compact data format.
.SH EXAMPLES
.TP 5
.B [1] reformat trainp.1 trainp.4
Convert the input trajectory file in format 1 (ASCII) to format 4 (netCDF).
