gmtconvert

GMTCONVERT(l)															     GMTCONVERT(l)

NAME

       gmtconvert - Convert between ASCII and binary 1-D tables

SYNOPSIS

       gmtconvert [ inputfiles] [ -H[nrec] ] [ -M[flag] ] [ -V ] [ -: ] [ -bi[s]n ] [ -bo[s][n] ]

DESCRIPTION

       gmtconvert  reads  its  standard  input	[or  inputfiles] and writes out the information to standard output. Its main purpose is to convert
       between binary and ASCII data tables. Input (and hence output) may have multiple subheaders if -M is selected.

       datafile(s)
	      ASCII (or binary, see -bi) file(s) holding a number of data columns.

OPTIONS

       -H     Input file(s) has Header record(s). Number of header records can be changed by editing your .gmtdefaults file. If used, GMT  default
	      is 1 header record.

       -M     Multiple	segment file(s). Segments are separated by a special record.  For ASCII files the first character must be flag [Default is
	      '>'].  For binary files all fields must be NaN.

       -V     Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].

       -:     Toggles between (longitude,latitude) and (latitude,longitude) input/output. [Default  is	(longitude,latitude)].	 Applies  to  geo-
	      graphic coordinates only.

       -bi    Selects binary input. Append s for single precision [Default is double].	Append n for the number of columns in the binary file(s).

       -bo    Selects binary output. Append s for single precision [Default is double].

EXAMPLES

       To convert the binary file test.b (single precision) with 4 columns to ASCII, try

       gmtconvert test.b -bis4 > test.dat

       To convert the multiple segment ASCII table test.d to a double precision binary file, try

       gmtconvert test.d -M -bo > test.b
