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
