B.1.3 NetCDF tables
</H2>
<A NAME="29534"></A>
<A NAME="29535"></A>

<P>
More and more programs are now producing binary data in the netCDF format, and so <A NAME="tex2html1646"
  HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> programs
started to support tabular netCDF data (files containing one or more 1-dimensional arrays) starting with <A NAME="tex2html1647"
  HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> version 4.3.0.
Because of the meta data contained in those files, reading them is much less complex than reading native binary tables,
and even than ASCII tables. <A NAME="tex2html1648"
  HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> programs will read as many 1-dimensional columns as are needed by the program, starting with the first
1-dimensional it can find in the file. To specifically specify which variables are to be read,
append the suffix <B>?</B><I>var1</I><B>/</B><I>var2</I><B>/</B><I>...</I> to the netCDF file name
or add the option <B>-bic</B><I>var1</I><B>/</B><I>var2</I><B>/</B><I>...</I>, where <I>var1</I>, <I>var2</I>, etc. are the names of the variables to be processed. The latter option is particularly practical when more
than one file is read: the <B>-bic</B> option will apply to all files.
Currently, <A NAME="tex2html1649"
  HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> only reads, but does not write, netCDF tabular data.
