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 multi-
ple 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
geographic 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).
-O Selects Overlay plot mode [Default initializes a new plot sys-
tem].
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 preci-
sion binary file, try
gmtconvert test.d -M -bo > test.b
