Sequence-level differences to consider
- Point mutations
- silent/synonymous
- missense
- nonsense
- translational stability (re: codon bias)?
- Deletions (and insertions)
- frame shift
- downstream effects?
- Add more here...
- Coding vs nonCoding seq
- We should be able to determine AUG and stop codons...
General coding questions / ideas
- How should we handle file input?
- How should we format the output?
- Generation of a set of test inputs.
- How can the identification of a class of differences be identified with a set of implementable conditions (ie how do you seperate out a duplication or an insertion from a rearrangement.
Using clustalw for sequence alignment
- clustalw can be used for performing multiple sequence alignments
- BioPython provides a wrapper for clustalw through the Bio.Clustalw package. However, clustalw needs to be downloaded and installed before it is accessible using your biopython scripts.
- As Zsun noticed, the BioPython cookbook has some outdated example code for accessing clustalw. An online Python Course in Bioinformatics by Katja Schuerer and Catherine Letondal has several better examples with correct code.
