To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

minmax

MINMAX(l)																 MINMAX(l)

NAME

       minmax - Find extreme values in data tables

SYNOPSIS

       minmax [ files] [ -C ] [ -D ] [ -H[nrec] ] [ -Idx[/dy] ] [ -L ] [ -M[flag] ] [ -: ] [ -bi[s][n] ]

DESCRIPTION

       minmax  reads  its  standard  input  [or from files] and finds the extreme values in each of the columns. It recognizes NaNs and will print
       warnings if the number of columns vary from record to record.  As an option, minmax will find the extent of the first two  columns  rounded
       up  and down to the nearest multiple of dx/dy. This output will be in the form -Rw/e/s/n which can be used directly in the command line for
       other programs, or simply in column form.

       xyzfile
	      ASCII [or binary, see -b] file(s) holding a fixed number of data columns.

OPTIONS

       -C     Report the min/max values per column in separate columns [Default uses <min/max> format]

       -D     Sets longitude discontinuity to the Dateline (-180/+180) [Default is Greenwich (0-360)].	Requires -L.

       -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.

       -I     Report  the  min/max of the first two columns to the nearest multiple of dx and dy, and output this in the form -Rw/e/s/n (unless -C
	      is set).

       -L     Indicates that the x column contains longitudes, which may be periodic in 360 degrees [Default assumes no periodicity].

       -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.

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

       -bi    Selects binary input. Append s for single precision [Default is double].	Append n for the number of columns in the binary  file(s).
	      [Default is 2 input columns].

EXAMPLES

       To find the extreme values in the file ship_gravity.xygd, try

       minmax ship_gravity.xygd

       Output should look like

       ship_gravity.xygd: N = 6992 <326.125/334.684> <-28.0711/-8.6837> <-47.7/177.6> <0.6/3544.9>

       To find the extreme values in the file track.xy to the nearest 5 units and use this region to draw a line using psxy, try

       psxy `minmax -I5 track.xy` track.xy -Jx1 -B5 -P > track.ps

       To find the min and max values for each column, but rounded to integers, try

       minmax junkfile -C -I1
