-Galaxy tool to select FASTA, QUAL, FASTQ or SFF sequences by ID
-===============================================================
-
-This tool is copyright 2011-2013 by Peter Cock, The James Hutton Institute
-(formerly SCRI, Scottish Crop Research Institute), UK. All rights reserved.
-See the licence text below.
-
-This tool is a short Python script (using Biopython library functions) to extract
-sequences from a FASTA, QUAL, FASTQ, or SFF file based on the list of IDs given
-by a column of a tabular file. The output order follows that of the tabular file,
-and if there are duplicates in the tabular file, there will be duplicates in the
-output sequence file.
-
-This tool is available from the Galaxy Tool Shed at:
-
-* http://toolshed.g2.bx.psu.edu/view/peterjc/seq_select_by_id
-
-See also the sister tools to filter sequence files according to IDs from column(s)
-of a tabular file (where the output order follows the sequence file, and any
-duplicate IDs are ignored) and rename sequences:
-
-* http://toolshed.g2.bx.psu.edu/view/peterjc/seq_filter_by_id
-* http://toolshed.g2.bx.psu.edu/view/peterjc/seq_rename
-
-
-Automated Installation
-======================
-
-This should be straightforward using the Galaxy Tool Shed, which should be
-able to automatically install the dependency on Biopython, and then install
-this tool and run its unit tests.
-
-
-Manual Installation
-===================
-
-There are just two files to install to use this tool from within Galaxy:
-
-* seq_select_by_id.py (the Python script)
-* seq_select_by_id.xml (the Galaxy tool definition)
-
-The suggested location is in the Galaxy folder tools/filters next to the tool
-for calling sff_extract.py for converting SFF to FASTQ or FASTA + QUAL.
-
-You will also need to modify the tools_conf.xml file to tell Galaxy to offer the
-tool. One suggested location is in the filters section. Simply add the line::
-
-    <tool file="filters/seq_select_by_id.xml" />
-
-If you wish to run the unit tests, also add this to tools_conf.xml.sample
-and move/copy the test-data files under Galaxy's test-data folder. Then::
-
-    $ ./run_functional_tests.sh -id seq_select_by_id
-
-You will also need to install Biopython 1.54 or later. That's it.

-**What it does**
-
-Takes a FASTA, QUAL, FASTQ or Standard Flowgram Format (SFF) file and produces a
-new sequence file (of the same format) containing only the records with identifiers
-in the tabular file (in the order from the tabular file).
-
-WARNING: If you have any duplicates in the tabular file identifiers, you will get
-duplicate sequences in the output.

+**What it does**
+
+Takes a FASTA, QUAL, FASTQ or Standard Flowgram Format (SFF) file and produces a
+new sequence file (of the same format) containing only the records with identifiers
+in the tabular file (in the order from the tabular file).
+
+WARNING: If you have any duplicates in the tabular file identifiers, you will get
+duplicate sequences in the output.
