 To read data written with PIDX we follow the same initialization process to create the <code>PIDX_access</code> and <code>PIDX_file</code> that we saw in the previous section.

@@ Line 43: / Line 43: @@
 If you want to write and read data in PIDX you just need to follow a few simple steps: - identify the per-process local domain - create a <code>PIDX_access</code>, it defines how you want to access the data (serial or parallel) - create or access a <code>PIDX_file</code>, it defines the dataset - define or read one or more <code>PIDX_variable</code> - write/read the variables

+=== How to write ===
 The data that we want to write from each processor can be considered as a ''box'' in the global domain. This ''box'' is represented by and ''offset'' (i.e. the position in the global domain) and a ''size'' (i.e. the number of elements in the box).

		+	The file ''FindPIDX.cmake'' is provided in the root installation directory after running make install. It configures PIDX_INCLUDE_DIR and PIDX_LIBRARIES for use by your application (e.g. via CMake).
		+	If you are using your custom Make file you can:
		+	* compile with -I/install/path/PIDX (add to CFLAGS).
		+	* link with -L/install/path/PIDX/lib -lpidx -lzfp (add to LDFLAGS).

 PIDX is an efficient parallel I/O library that reads and writes multiresolution data. PIDX is open source and available on GitHub: [https://github.com/sci-visus/PIDX/ PIDX]
-== Introduction ==
+== Examples ==
 In these examples we describe how to write and read data using the PIDX library. We consider a global 3D regular grid domain that we will call global domain (g). This global domain represents the grid space where all the data resides.
