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="tex2html1718" 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="tex2html1719" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> only reads, but does not write, netCDF tabular data. <P> <HR> <!--Navigation Panel--> <A NAME="tex2html5293" HREF="node182.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="next.png"></A> <A NAME="tex2html5287" HREF="node176.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="up.png"></A> <A NAME="tex2html5283" HREF="node180.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="prev.png"></A> <A NAME="tex2html5289" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="contents.png"></A> <A NAME="tex2html5291" HREF="node258.html"> <IMG WIDTH="43" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="index" SRC="index.png"></A> <BR> <B> Next:</B> <A NAME="tex2html5294" HREF="node182.html">B.2 Grid files</A> <B> Up:</B> <A NAME="tex2html5288" HREF="node176.html">B.1 Table data</A> <B> Previous:</B> <A NAME="tex2html5284" HREF="node180.html">B.1.2 Binary tables</A> <B> <A NAME="tex2html5290" HREF="node1.html">Contents</A></B> <B> <A NAME="tex2html5292" HREF="node258.html">Index</A></B> <!--End of Navigation Panel--> <ADDRESS> Paul Wessel 2011-02-27 </ADDRESS> </BODY> </HTML>
