<h2>Preamble<a class="headerlink" href="#preamble" title="Permalink to this headline">¶</a></h2>
<p>The Neo <tt class="xref py py-mod docutils literal"><span class="pre">io</span></tt> module aims to provide an exhaustive way of loading and saving several widely used data formats in electrophysiology.
The more these heterogeneous formats are supported, the easier it will be to manipulate them as Neo objects in a similar way.
Therefore the IO set of classes propose a simple and flexible IO API that fits many format specifications.
It is not only file-oriented, it can also read/write objects from a database.</p>
<p><a class="reference internal" href="#module-neo.io" title="neo.io"><tt class="xref py py-mod docutils literal"><span class="pre">neo.io</span></tt></a> can be seen as a <em>pure-Python</em> and open-source Neuroshare replacement.</p>
<dl class="docutils">
<dt>At the moment, there are 3 families of IO modules:</dt>
<dd><ol class="first last arabic simple">
<li>for reading closed manufacturers’ formats (Spike2, Plexon, AlphaOmega, BlackRock, Axon, ...)</li>
<li>for reading(/writing) formats from open source tools (KlustaKwik, Elan, WinEdr, WinWcp, PyNN, ...)</li>
<li>for reading/writing Neo structure in neutral formats (HDF5, .mat, ...) but with Neo structure inside (NeoHDF5, NeoMatlab, ...)</li>
</ol>
</dd>
</dl>
<p>Combining <strong>1</strong> for reading and <strong>3</strong> for writing is a good example of use: converting your datasets
to a more standard format when you want to share/collaborate.</p>
</div>
<div class="section" id="introduction">
<h2>Introduction<a class="headerlink" href="#introduction" title="Permalink to this headline">¶</a></h2>
<p>There is an intrinsic structure in the different Neo objects, that could be seen as a hierachy with cross-links. See <a class="reference internal" href="core.html"><em>Neo core</em></a>.
The highest level object is the <tt class="xref py py-class docutils literal"><span class="pre">Block</span></tt> object, which is the high level container able to encapsulate all the others.</p>
<p>A <tt class="xref py py-class docutils literal"><span class="pre">Block</span></tt> has therefore a list of <tt class="xref py py-class docutils literal"><span class="pre">Segment</span></tt> objects, that can, in some file formats, be accessed individually.
Depending on the file format, i.e. if it is streamable or not, the whole <tt class="xref py py-class docutils literal"><span class="pre">Block</span></tt> may need to be loaded, but sometimes
particular <tt class="xref py py-class docutils literal"><span class="pre">Segment</span></tt> objects can be accessed individually.
Within a <tt class="xref py py-class docutils literal"><span class="pre">Segment</span></tt>, the same hierarchical organisation applies.
A <tt class="xref py py-class docutils literal"><span class="pre">Segment</span></tt> embeds several objects, such as <tt class="xref py py-class docutils literal"><span class="pre">SpikeTrain</span></tt>,
<tt class="xref py py-class docutils literal"><span class="pre">AnalogSignal</span></tt>, <tt class="xref py py-class docutils literal"><span class="pre">AnaloSignalArray</span></tt>, <tt class="xref py py-class docutils literal"><span class="pre">EpochArray</span></tt>, <tt class="xref py py-class docutils literal"><span class="pre">EventArray</span></tt>
(basically, all the different Neo objects).</p>
<p>Depending on the file format, these objects can sometimes be loaded separately, without the need to load the whole file.
If possible, a file IO therefore provides distinct methods allowing to load only particular objects that may be present in the file.
The basic idea of each IO file format is to have, as much as possible, read/write methods for the individual encapsulated objects,
and otherwise to provide a read/write method that will return the object at the highest level of hierarchy
(by default, a <tt class="xref py py-class docutils literal"><span class="pre">Block</span></tt> or a <tt class="xref py py-class docutils literal"><span class="pre">Segment</span></tt>).</p>
<p>The <a class="reference internal" href="#module-neo.io" title="neo.io"><tt class="xref py py-mod docutils literal"><span class="pre">neo.io</span></tt></a> API is a balance between full flexibility for the user (all <tt class="xref py py-meth docutils literal"><span class="pre">read_XXX()</span></tt> methods are enabled)
and simple, clean and understandable code for the developer (few <tt class="xref py py-meth docutils literal"><span class="pre">read_XXX()</span></tt> methods are enabled).
This means that not all IOs offer the full flexibility for partial reading of data files.</p>
</div>
<div class="section" id="one-format-one-class">
<h2>One format = one class<a class="headerlink" href="#one-format-one-class" title="Permalink to this headline">¶</a></h2>
<p>The basic syntax is as follows. If you want to load a file format that is implemented in a generic <tt class="xref py py-class docutils literal"><span class="pre">MyFormatIO</span></tt> class:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="kn">from</span> <span class="nn">neo.io</span> <span class="kn">import</span> <span class="n">MyFormatIO</span>

<p>In some cases you may not want to load everything in memory because it could be too big.
For this scenario, two options are available:</p>
<blockquote>
<div><ul class="simple">
<li><tt class="docutils literal"><span class="pre">lazy=True/False</span></tt>. With <tt class="docutils literal"><span class="pre">lazy=True</span></tt> all arrays will have a size of zero, but all the metadata will be loaded. lazy_shape attribute is added to all object that
inheritate Quantitities or numpy.ndarray (AnalogSignal, AnalogSignalArray, SpikeTrain) and to object that have array like attributes (EpochArray, EventArray)
In that cases, lazy_shape is a tuple that have the same shape with lazy=False.</li>
<li><tt class="docutils literal"><span class="pre">cascade=True/False</span></tt>. With <tt class="docutils literal"><span class="pre">cascade=False</span></tt> only one object is read (and <em>one_to_many</em> and <em>many_to_many</em> relationship are not read).</li>
</ul>
</div></blockquote>

<p>Some IOs support advanced forms of lazy loading, cascading or both (these features are currently limited to the HDF5 IO, which supports both forms).</p>
<ul>
<li><p class="first">For lazy loading, these IOs have a <tt class="xref py py-meth docutils literal"><span class="pre">load_lazy_object()</span></tt> method that takes a single parameter: a data object previously loaded by the same IO
in lazy mode. It returns the fully loaded object, without links to container objects (Segment etc.). Continuing the lazy example above:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="n">lazy_sig</span> <span class="o">=</span> <span class="n">seg</span><span class="o">.</span><span class="n">analogsignals</span><span class="p">[</span><span class="mi">0</span><span class="p">]</span> <span class="c"># Empty signal</span>

</pre></div>
</div>
</li>
<li><p class="first">For lazy cascading, IOs have a <tt class="xref py py-meth docutils literal"><span class="pre">load_lazy_cascade()</span></tt> method. This method is not called directly when interacting with the IO, but its
presence can be used to check if an IO supports lazy cascading. To use lazy cascading, the cascade parameter is set to <tt class="docutils literal"><span class="pre">'lazy'</span></tt>:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="n">block</span> <span class="o">=</span> <span class="n">reader</span><span class="o">.</span><span class="n">read</span><span class="p">(</span><span class="n">cascade</span><span class="o">=</span><span class="s">'lazy'</span><span class="p">)</span>
</pre></div>
</div>
<p>You do not have to do anything else, lazy cascading is now active for the object you just loaded. You can interact with the object in the same way
as if it was loaded with <tt class="docutils literal"><span class="pre">cascade=True</span></tt>. However, only the objects that are actually accessed are loaded as soon as they are needed:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="k">print</span><span class="p">(</span><span class="n">block</span><span class="o">.</span><span class="n">recordingchannelgroups</span><span class="p">[</span><span class="mi">0</span><span class="p">]</span><span class="o">.</span><span class="n">name</span><span class="p">)</span> <span class="c"># The first RecordingChannelGroup is loaded</span>
<span class="gp">>>> </span><span class="k">print</span><span class="p">(</span><span class="n">block</span><span class="o">.</span><span class="n">segments</span><span class="p">[</span><span class="mi">0</span><span class="p">]</span><span class="o">.</span><span class="n">analogsignals</span><span class="p">[</span><span class="mi">1</span><span class="p">])</span> <span class="c"># The first Segment and its second AnalogSignal are loaded</span>
</pre></div>
</div>
<p>Once an object has been loaded with lazy cascading, it stays in memory:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="gp">>>> </span><span class="k">print</span><span class="p">(</span><span class="n">block</span><span class="o">.</span><span class="n">segments</span><span class="p">[</span><span class="mi">0</span><span class="p">]</span><span class="o">.</span><span class="n">analogsignals</span><span class="p">[</span><span class="mi">0</span><span class="p">])</span> <span class="c"># The first Segment is already in memory, its first AnalogSignal is loaded</span>

<dt>The <a class="reference internal" href="#module-neo.io" title="neo.io"><tt class="xref py py-mod docutils literal"><span class="pre">neo.io</span></tt></a> API is designed to be simple and intuitive:</dt>
<dd><ul class="first last simple">
<li>each file format has an IO class (for example for Spike2 files you have a <tt class="xref py py-class docutils literal"><span class="pre">Spike2IO</span></tt> class).</li>
<li>each IO class inherits from the <tt class="xref py py-class docutils literal"><span class="pre">BaseIO</span></tt> class.</li>
<li>each IO class can read or write directly one or several Neo objects (for example <tt class="xref py py-class docutils literal"><span class="pre">Segment</span></tt>, <tt class="xref py py-class docutils literal"><span class="pre">Block</span></tt>, ...): see the <tt class="xref py py-attr docutils literal"><span class="pre">readable_objects</span></tt> and <tt class="xref py py-attr docutils literal"><span class="pre">writable_objects</span></tt> attributes of the IO class.</li>
<li>each IO class supports part of the <a class="reference internal" href="api_reference.html#module-neo.core" title="neo.core"><tt class="xref py py-mod docutils literal"><span class="pre">neo.core</span></tt></a> hierachy, though not necessarily all of it (see <tt class="xref py py-attr docutils literal"><span class="pre">supported_objects</span></tt>).</li>
<li>each IO class has a <tt class="xref py py-meth docutils literal"><span class="pre">read()</span></tt> method that returns a list of <tt class="xref py py-class docutils literal"><span class="pre">Block</span></tt> objects. If the IO only supports <tt class="xref py py-class docutils literal"><span class="pre">Segment</span></tt> reading, the list will contain one block with all segments from the file.</li>
<li>each IO class that supports writing has a <tt class="xref py py-meth docutils literal"><span class="pre">write()</span></tt> method that takes as a parameter a list of blocks, a single block or a single segment, depending on the IO’s <tt class="xref py py-attr docutils literal"><span class="pre">writable_objects</span></tt>.</li>
<li>each IO is able to do a <em>lazy</em> load: all metadata (e.g. <tt class="xref py py-attr docutils literal"><span class="pre">sampling_rate</span></tt>) are read, but not the actual numerical data. lazy_shape attribute is added to provide information on real size.</li>
<li>each IO is able to do a <em>cascade</em> load: if <tt class="docutils literal"><span class="pre">True</span></tt> (default) all child objects are loaded, otherwise only the top level object is loaded.</li>
<li>each IO is able to save and load all required attributes (metadata) of the objects it supports.</li>
