| '''Beginning Perl'''<br />
This time, both novices and experienced programmers do the same homework, with one small difference in the use of the program.
 
Recall from the first class where I introduced the FASTA-format. In this format, sequence data is recorded as follows:
<pre>>SequenceID_info1_info2
atgcgtgatg...</pre>
 
Of course, the ID portion is itself not standardized, and the sequence can also be an amino acid sequence. For simplicity, let's assume that in the ID field, you have a "Strain" name followed by a "protein" name, separated by an underscore (_). You will write a program to read a FASTA file with the ID format described above, and a nucleotide sequence. For both novice-level and experienced level programmers, your program will:
 
# Pick out the strain name, the protein name, and the nucleotide sequence.
# Calculate he length of each sequence.
# Calculate the GC content (in percent) of each sequence.
# Calculate the percent composition of each nucleotide (base composition).
 
'''Novice-level task:'''
 
Your program will just print the above information '''for all sequences''', in a readable form. Sample output could be:
<pre>Strain: B31
Protein: ospA
Seq Length: 819
GC content: 33.58%
Base composition: A 42.98 %, T 23.44 %, C 14.77 %, G 18.80 %</pre>
If your percentages have more than 2 decimal places, '''that's OK.'''
 
'''Experienced-level task:'''
 
The only difference from novices is that your program will '''ask the user for the name of a strain and protein, separated by an underscore''' (ie, B31_opsA). Once given that input, it will print the exact same output as above, but only for the sequence described by that input. If the input doesn't exist, it will say so and exit. Your program will '''continue to ask the user for the sequence ID''' until the user types 'quit' or they give an invalid sequence ID. You can do this by using a while loop.
 
'''Notes'''
 
Calculating the GC content and the base composition is easy if you make use of the tr (transliterate) function as described at the bottom of page 232, and divide the result by the sequence length. GC content is just the sum of total G and C nucleotides, divided by the sequence length. I do want '''percents''', so remember to multiply the results by 100 and to append a '%' at the end.
 
Getting the strain name and the protein name separately can be accomplished with the split() function (check new slides or search on the internet).
 
You will test your program the with the file /data/yoda/b/student.accounts/bio425_2011/data/Borrelia_osp.dna.fasta as input. You don't have to include the file itself with your homework, but I do still want you to copy the program output and submit it with your assignment.
 
Again, the program cannot use any outside dependencies/modules such as BioPerl (supposing you know how to use it.) Besides that, you can implement it however you like. If you know about references, '''it is possible to do this assignment without using them.'''

| '''BioPerl Assignment'''
 
For this assignment, you will use the .predict file you made with glimmer in [[#February_19 | assignment 3]].
 
If connecting from home: open gedit '''before''' logging on to mysql.
 
For BioPerl to work, you '''must''' log on to mysql.
 
'''Complete the assignment by following these steps.''' Make sure each part works '''before''' trying to solve the next part:
# Make a perl script that reads each line from the .predict file that describes a gene (skip the heading line).
# Save each line ('''hint:''' array, anyone?)
# Now, in the same script, use '''Bio::SeqIO''' to read the lp17.fas file '''and get a Bio::Seq object.'''
# Go through each line saved from the .predict file. Remember: these are predicted orfs:
## For each of these, '''extract the start and stop positions and "strand" values''' (the three values following the orf name).
## If the strand starts with a '-', it means the orf is on the reverse complement, so you need to use the Bio::Seq method "revcom".
## Now, extract the orf sequence using the start & stop values using the Bio::Seq method "subseq", paying special attention to sequences on on the '-' strand.
## Print both the DNA sequence AND the protein sequence.
 
See these sample scripts for how to use revcom and subseq:
<pre>../bio425_2011/sample-perl-scripts/revcom_translate_seq.pl
../bio425_2011/sample-perl-scripts/subseq.pl
</pre>
 
And I linked to the HOWTO above in case you forgot.
 
'''Output should be informative:'''
<pre>
ORF: orf00002
DNA: ...
Protein: ...

Continue work on the assignment we began in class. It is reproduced below, with some added functionality.
 
Your script will:
 
# Retrieve TEN orfs from the orf table that belong to the strain Pko.
# Find and store the sequences described by those orfs and their lengths.
# Determine if the orf is on the reference or reverse complement strand, and use that information to print the correct sequence.
# Print the orf name, sequence, and the length for each orf.
# '''In addition to printing the above information to the screen,''' write out the sequence information '''(in FASTA format)''' to a file
called "Pko_orfs.fasta". The sequence ID should be of the form:
Pko_orfname
 
Note that the above will require the use of BioPerl.
 
 
For those looking for extra challenges, you can try adding the following:
 
* Ask the user for the strain and contig *names* that they want orfs from, and only retrieve those rows. This means you must find a way
of obtaining their respective IDs from just their names. Make sure the sequence IDs are informative. They should look like this:
strainname_contigname_orfname
* If asking users for input, fail if they gave a strain or contig name which does not exist in the database.
* Also if asking users for input, the output file's name should be changed to reflect the chosen strain.
* Ask the user the minimum length the orf is allowed to be, and only print orfs as long, or longer, than what the user specifies.
 
 
Sample scripts will go up slowly, over time, including example SQL statements.

Course Description

Background

Biomedical research is becoming a high-throughput science. As a result, information technology plays an increasingly important role in biomedical discovery. Bioinformatics is a new interdisciplinary field formed between molecular biology and computer science.

Contents

This course will introduce both bioinformatics theories and practices. Topics include: database searching, sequence alignment, molecular phylogenetics, structure prediction, and microarray analysis. The course is held in a UNIX-based instructional lab specifically configured for bioinformatics applications. Each session consists of a first-half instruction on bioinformatics theories and a second-half session of hands-on exercises.

Learning Goals

Students are expected to be able to:

  • Approach biological questions evolutionarily ("Tree-thinking")
  • Evaluate and interpret computational results statistically ("Statistical-thinking")
  • Formulate informatics questions quantitatively and precisely ("Abstraction")
  • Design efficient procedures to solve problems ("Algorithm-thinking")
  • Manipulate high-volume textual data using UNIX tools, Perl/BioPerl, R, and Relational Database ("Data Visualization")

Pre-requisites

This 3-credit course is designed for upper-level undergraduates and graduate students. Prior experiences in the UNIX Operating System and at least one programming language are required. Hunter pre-requisites are CSCI132 (Practical Unix and Perl Programming) and BIOL300 (Biochemistry) or BIOL302 (Molecular Genetics), or permission by the instructor.

Textbook

Krane & Raymer (2003). Fundamental Concepts of Bioinformatics. Pearson Education, Inc. (ISBN 0-8053-4633-3)

This book should be available in the Hunter Bookstore, as well as through several popular retailers and resellers online.

Grading & Academic Honesty

Hunter College regards acts of academic dishonesty (e.g., plagiarism, cheating on examinations, obtaining unfair advantage, and falsification of records and official documents) as serious offenses against the values of intellectual honesty. The College is committed to enforcing the CUNY Policy on Academic Integrity and will pursue cases of academic dishonesty according to the Hunter College Academic Integrity Procedures.

Student performance will be evaluated by weekly assignments and projects. While these are take-home projects and students are allowed to work in groups and answers to some of the questions are provided in the back of the textbook, students are expected to compose the final short answers, computer commands, and code independently. There are virtually an unlimited number of ways to solve a computational problem, as are ways and personal styles to implement an algorithm. Writings and blocks of codes that are virtually exact copies between individual students will be investigated as possible cases of plagiarism (e.g., copies from the Internet, text book, or each other). In such a case, the instructor will hold closed-door exams for involved individuals. Zero credits will be given to ALL involved individuals if the instructor considers there is enough evidence for plagiarism. To avoid being investigated for plagiarism, Do Not Copy from Others & Do Not Let Others Copy Your Work.

Submit assignments in Printed Hard Copies. Email attachments will NOT be accepted. Each assignment will be graded based on timeliness (10%), completeness (30%), whether executable or having major errors (20%), correctness of the final output (20%), algorithm efficiency (10%), and cleanness and readability in programming styles (10%).

The grading scheme for the course, is as follows (Subject to some change. You will be notified with sufficient time):

  • Assignments (50%): 10 exercises.
  • Mid-term (20%): In class Assignment + Take home to be collected on the same day.
  • Final exam (20%)
  • Classroom Q & A (5%): Read the chapters before lecture.
  • Attendance (5%): 1-2 absences = -2.5%. More than 2 = -5%.

Programming Assignment Expectations

All code must begin with the lines in the Perl slides, without exception. For each assignment, unless otherwise stated, I would like the full text of the source code. Since you cannot print using the text editor in the lab (even if you are connected from home), you must copy and paste the code into a word processor or a local text editor. If you are using a word processor, change the font to a fixed-width/monospace font. On Windows, this is usually Courier.

Code indentation is your personal taste, so long as it is consistent and readable. Use comments whenever you think either the code is unclear, or simply as a guideline for yourself. Well-commented code improves readability, but be careful not overdo it.

Also, unless otherwise stated, both the input and the output of the program must be submitted as well. This should also be in fixed-width font, and you should label it in such a way so that I know it is the program's input/output. This is so that I know that you've run the program, what data you have used, and what the program produced.

If you are working from the lab, one option is to email the code to yourself, change the font, and then print it somewhere else as there is no printer in the lab.
