Importing data from SRA, ENA, or GenBank
--------------------------------------------------------------------------------

If you have downloaded a data set from GenBank, SRA, or ENA, the format of the
sequences headers are different from the raw Roche 454 and Illumina header
format. As such, they may or may not be compatible with pRESTO (depending on
how the headers have been modified by the sequence archive). :ref:`ConvertHeaders`
allows you to change incompatible header formats into
the pRESTO format. For example, to convert from SRA or ENA headers the
:program:`sra` subcommand would be used:

.. code-block:: none

    ConvertHeaders.py sra -s reads.fastq

:ref:`ConvertHeaders` provides the following conversion subcommands:
