**What it does**

Falco_ is a high-speed emulation of the popular FastQC software for quality control of sequencing data.

💚️ With its superior performance Falco saves computational resources and gives you back results faster than FastQC.

We recommend it for most use cases (but see below for exceptions). 💚️

The main functions of Falco are very similar to those of FastQC:

- Import of data from BAM, SAM or FastQ/FastQ.gz files (any variant),
- Providing a quick overview to tell you in which areas there may be problems
- Summary graphs and tables to quickly assess your data
- Export of results to an HTML based permanent report
- Offline operation to allow automated generation of reports without running the interactive application

.. class:: infomark

The plain text report generated by Falco can be used as a "FastQC" report in MultiQC and its data is very similar though not 100% identical to that generated by FastQC on the same inputs.

.. class:: Warning mark

    In the following situations, FastQC is still a better solution than this version of Falco:

- your input is bz2-compressed fastq

  Falco doesn't currently support fastq.bz2 as input format meaning Galaxy has to perform a relatively slow format conversion before running the tool, which together makes the analysis slower than with FastQC.

- you are interested in PolyA and PolyG statistics in the Adapter Content section of the quality report

  Falco doesn't currently calculate statistics for these "Adapters" by default.

- your input consists of *mapped* reads in SAM/BAM format

  Due to a bug in the current version of Falco, reads mapped to the reverse strand of the reference genome are not handled correctly and reported metrics are wrong!

-----

**Inputs and outputs**

The Falco_ development repo includes very good documentation.
A summary of it follows below for those in a tearing hurry.

This wrapper will accept a Galaxy fastq, fastq.gz, sam or bam as the input read file to check.
It will also take an optional file containing a list of contaminants information, in the form of
a tab-delimited file with 2 columns, name and sequence. As another option the tool takes a custom
limits.txt file that allows setting the warning thresholds for the different modules and also specifies
which modules to include in the output.

The tool produces a basic text and a HTML output file that contain all of the results, including the following:

- Basic Statistics
- Per base sequence quality
- Per sequence quality scores
- Per base sequence content
- Per base GC content
- Per sequence GC content
- Per base N content
- Sequence Length Distribution
- Sequence Duplication Levels
- Overrepresented sequences
- Adapter Content

All except Basic Statistics and Overrepresented sequences are plots.
