**What is does**

BAMTools filter is a very powerful utility to perform complex filtering of BAM files. It is based on BAMtools suite of tools by Derek Barnett (https://github.com/pezmaster31/bamtools).

-----

**How it works**

The tool use logic relies on the three concepts: (1) input BAM, (2) groups, and (3) filters.

*Input BAM(s)*

The input BAM is self-explanatory. This is the dataset you will be filtering. The tool can accept just one or multiple BAM files. To filter on multiple BAMs just add them by clicking **Add new BAM dataset(s) to filter**

*Conditions and Filters*

Conditions for filtering BAM files can be arranged in **Groups and Filters**. While it can be confusing at first this is what gives ultimate power to this tools. So try to look at the examples we are supplying below.

-----

**Example 1. Using a single filter**

When filtering on a single condition there is no need to worry about filters and conditions. Just choose a filter from the **Select BAM property to filter on:** dropdown and enter a value (or click a checkbox for binary filters).
For example, for retaining reads with mapping quality of at least 20 one would set the tool interface as shown below:

.. image:: single-filter.png

-----

**Example 2. Using multiple filters**

Now suppose one needs to extract reads that (1) have mapping quality of at least 20, (2) contain at least 1 mismatch, and (3) are mapping onto forward strand only.
To do so we will use three filters as shown below (multiple filters are added to the interface by clicking on the **Add new Filter** button):

.. image:: multiple-filters.png

In this case (you can see that the three filters are grouped within a single Condition - **Condition 1**) the filter too use logical **AND** to perform filtering.
In other words only reads that (1) have mapping quality of at least 20 **AND** (2) contain at least 1 mismatch **AND** are mapping onto forward strand will be returned in this example.

-----

**Example 3. Complex filtering with multiple conditions**

Suppose now you would like to select **either** reads that (**1**) have (*1.1*) no mismatches and (*1.2*) are on the forward strand **OR** (**2**) reads that have (*2.1*)
at least one mismatch and (*2.2*) are on the reverse strand. In this scenario we have to set up two conditions: (**1**) and (**2**) each with two filters: *1.1* and *1.2* as well as *2.1* and *2.2*.
The following screenshot expalins how this can be done:

.. image:: complex-filters.png

-----

**Example 4. Even more complex filtering with Rules**

In the above example we have used two conditions (Condition 1 and Condition 2). Using multiple conditions allows to combine them and a variety of ways to enable even more powerful filtering.
For example, suppose get all reads that (**1**) do NOT map to mitochondria and either (**2**) have mapping quality over 20, or (**3**) are in properly mapped pairs. The logical rule to enable such
filtering will look like this::

 !(1) & (2 | 3)

Here, numbers 1, 2, and 3 represent conditions. The following screenshot illustrates how to do this in Galaxy:

.. image:: rule.png

There are three conditions here, each with a single filter. A text entry area that can be opened by clicking on the **Would you like to set rules?** checkbox enables you to enter a rule.
Here numbers correspond to numbers of conditions as they are shown in the interface. E.g., 1 corresponds to condition 1, 2 to condition 2 and so on... In human language this means::

 NOT condition 1 AND (condition 2 OR condition 3)

-----

**JSON script file**

This tool produces two outputs. One of the them is a BAM file containing filtered reads. The other is a JSONified script. It can help you to see how your instructions are sent to BAMTools.
For instance, the example 4 looks like this in the JSON form::

       {
        "filters":
        [
          { "id": "1",
            "tag":"NM:=0",
            "isReverseStrand":"false"
          },
          { "id": "2",
            "tag":"NM:>0",
            "isReverseStrand":"true"
          }
        ]
      }
