XA0; & #XA0; Appendix: Useful stuff about Python& #XA0; & #XA0; Introduction& #XA0; & #XA0; What is Biopython? The Biopython Project is an international association of developers of freely available Python (http: //www. Python is an object oriented, interpreted, flexible language that is becoming increasingly popular for scientific computing. Python is easy to learn, has a very clear syntax and can easily be extended with modules written in C, C++ or FORTRAN. The Biopython web site (http: //www. Python- based software for bioinformatics use and research. Basically. the goal of Biopython is to make it as easy as possible to use Python. Biopython features include parsers for various Bioinformatics. BLAST, Clustalw, FASTA, Genbank..), access to online. NCBI, Expasy..), interfaces to common and not- so- common. Clustalw, DSSP, MSMS..), a standard sequence class, various. KD tree data structure etc. Is & #X2. 01. C; Bio. Python& #X2. D; OK? The correct capitalization is & #X2. C; Biopython& #X2. D; , not & #X2. C; Bio. Python& #X2. D; (even though. that would have matched Bio. Perl, Bio. Java and Bio. Ruby). What is going wrong with my print commands? This tutorial now uses the Python 3 style print function. In general you need to add this magic. Python scripts to use the print function. Python 2. 6 and 2. This naming. was used until June 2. Biopython 1. 6. 8. If the version string ends with & #X2. C. dev< number> & #X2. D; like. & #X2. C; 1. 6. 8. dev. 0& #X2. D; , again you don& #X2. Where is the latest version of this document? If you download a Biopython source code archive, it will include the. HTML and PDF formats. The latest published. What is wrong with my sequence comparisons? There was a major change in Biopython 1. Seq and. Mutable. Seq classes (and subclasses) use simple string- based. Older versions of Biopython would use instance- based comparison. Seq objects which you can do explicitly with. If you still need to support old versions of Biopython, use these. See Section& #XA0; 3. Why is the. Seqobject missing the upper & lower methods described in this Tutorial? You need Biopython 1. Alternatively, use str(my. They insist on handles! You need Biopython 1. Section& #XA0; 2. They insist on a list or iterator! You need Biopython 1. The module imports fine but there is no parse function! You need Biopython 1. Why has my script using. Bio. Entrez. efetch()stopped working? This could be due to NCBI changes in February 2. EFetch 2. 0. Check things like the gap penalties and expectation threshold. Why doesn& #X2. Bio. Blast. NCBIXML. The module imports but there is no read function! You need Biopython 1. Or, use next(Bio. Blast. NCBIXML. parse(..)) instead. Why doesn& #X2. Seq. Recordobject have aletter? The modules import fine but there is no convert function! You need Biopython 1. Alternatively, combine the parse and write. Sections& #XA0; 5. XA0; 6. 2. 1). Why doesn& #X2. Bio. Seq. IO. index()work? The module imports fine but there is no index function! You need Biopython 1. Why doesn& #X2. Bio. Seq. IO. index? The module imports fine but there is no index? The. Bio. Alignmodule imports fine but this class isn& #X2. You need Biopython 1. Alternatively, the older Bio. Align. Generic. Alignment class supports some of its functionality, but using this is now discouraged. Why can& #X2. I run command line tools directly from the application wrappers? You need Biopython 1. Alternatively, use the Python subprocess module directly. I looked in a directory for code, but I couldn& #X2. Where& #X2. 01. One thing to know is that we put code in . If you are not used to looking for code in this file this can be confusing. The reason we do this is to make the imports easier for users. For instance, instead of having to do a & #X2. C; repetitive& #X2. D; import like from Bio. Gen. Bank import Gen. Bank, you can just use from Bio import Gen. Bank. Why does the code from CVS seem out of date? In late September 2. Biopython 1. 5. 2, we switched from using CVS to git, a distributed version control system. The old CVS server will remain available as a static and read only backup, but if you want to grab the latest code, you& #X2. See our website for more details. Why doesn& #X2. Bio. Fastawork? We deprecated the Bio. Fasta module in Biopython 1. August 2. 00. 9) and removed it in Biopython 1. August 2. 01. 0). There is a brief example showing how to convert old code to use Bio. Seq. IO instead in the DEPRECATED file. For more general questions, the Python FAQ pages http: //www. XA0; & #XA0; Quick Start & #X2. What can you do with Biopython? This section is designed to get you started quickly with Biopython, and to give a general overview of what is available and how to use it. All of the examples in this section assume that you have some general working knowledge of Python, and that you have successfully installed Biopython on your system. If you think you need to brush up on your Python, the main Python web site provides quite a bit of free documentation to get started with (http: //www. Since much biological work on the computer involves connecting with databases on the internet, some of the examples will also require a working internet connection in order to run. Now that that is all out of the way, let& #X2. Biopython.& #XA0; & #XA0; General overview of what Biopython provides. As mentioned in the introduction, Biopython is a set of libraries to provide the ability to deal with & #X2. C; things& #X2. D; of interest to biologists working on the computer. In general this means that you will need to have at least some programming experience (in Python, of course!) or at least an interest in learning to program. Biopython& #X2. X2. 01. 9; t exist and contributing it to Biopython, please go ahead!). So Biopython& #X2. One thing to note about Biopython is that it often provides multiple ways of & #X2. C; doing the same thing.& #X2. D; Things have improved in recent releases, but this can still be frustrating as in Python there should ideally be one right way to do something. However, this can also be a real benefit because it gives you lots of flexibility and control over the libraries. The tutorial helps to show you the common or easy ways to do things so that you can just make things work. To learn more about the alternative possibilities, look in the Cookbook (Chapter& #XA0; 2. Advanced section (Chapter& #XA0; 2. X2. 01. C; docstrings& #X2. D; (via the Python help command, or the API documentation) or ultimately the code itself.& #XA0; & #XA0; Working with sequences. Disputably (of course!), the central object in bioinformatics is the sequence. Thus, we& #X2. Biopython mechanisms for dealing with sequences, the Seq object, which we& #X2. Chapter& #XA0; 3. Most of the time when we think about sequences we have in my mind a string of letters like & #X2. AGTACACTGGT& #X2. You can create such Seq object with this sequence as follows - the & #X2. C; > > > & #X2. D; represents the Python prompt followed by what you would type in: > > > from Bio. Seq import Seq. > > > my. We& #X2. 01. 9; ll talk more about alphabets in Chapter& #XA0; 3. In addition to having an alphabet, the Seq object differs from the Python string in the methods it supports. You can& #X2. This holds a sequence (as a Seq object) with additional annotation including an identifier, name and description. The Bio. Seq. IO module for reading and writing sequence file formats works with Seq. Record objects, which will be introduced below and covered in more detail by Chapter& #XA0; 5. This covers the basic features and uses of the Biopython sequence class. After all, if there wasn& #X2. Since I love plants, I think we& #X2. Having just completed a recent trip to our local greenhouse, we& #X2.
