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
