GMTCONVERT

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 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).

−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
