Add Dayhoff encoding of amino acids #689

olgabot · 2019-06-29T20:54:21Z

The Dayhoff encoding of amino acids was created by Margaret Oakley Dayhoff, arguably the first bioinformatician, and uses a lossy encoding of amino acid sequences. I'm interested in adding this feature to compare sequences across large evolutionary distances without penalizing minor residue changes.

Amino acid	Property	Dayhoff
C	Sulfur polymerization	a
A, G, P, S, T	Small	b
D, E, N, Q	Acid and amide	c
H, K, R	Basic	d
I, L, M, V	Hydrophobic	e
F, W, Y	Aromatic	f

proteins. BMC Bioinformatics, 9(1), 1029–11.

Is it mergeable?
make test Did it pass the tests?
make coverage Is the new code covered?
Did it change the command-line interface? Only additions are allowed
without a major version increment. Changing file formats also requires a
major version number increment.
Was a spellchecker run on the source code and documentation after
changes were made?

~~Yes, I'll remove the irrelevant 10x barcode commits..~~ -- rebased and force-pushed

yay!!

This PR is proving complicated because it adds a new molecule type which touches basically everything...

Should I be worried about this?

luizirber · 2019-07-07T01:56:11Z

@olgabot I'm also seeing this segfault under Linux, I think there is something awry in the _dna_to_aa function. I'll take a closer look.

(BTW, awesome PR!)

olgabot · 2019-07-07T18:14:08Z

@olgabot I'm also seeing this segfault under Linux, I think there is something awry in the _dna_to_aa function. I'll take a closer look.

The logic of getting an amino acid reside had to get rewritten with the addition of dayhoff and is definitely not something I'm super attached to. So feel free to rewrite it in a way that makes more sense. I focused on just getting it working...

(BTW, awesome PR!)

aww thanks! 😊

luizirber · 2019-07-07T18:58:18Z

@olgabot I sent a PR to your branch, https://github.com/czbiohub/sourmash/pull/3

It keeps the logic from the previous translation unchanged, and avoid adding the xxN codons to the original table. Dayhoff encoding should stay the same (but can you check again the change from residue to codon?)

UPDATE: I'm wrong, sorry. you need to check the residue, oops. I'll fix it.
UPDATE 2: Fixed.

olgabot · 2019-07-09T15:54:26Z

Cool now I'm getting a fun error because I added dayhoff conversion to add_protein. I thought that aa_to_dayhoff is in the right place in kmer_min_hash.hh but apparently it's not getting detected? Not 100% sure what's happening here

Yet somehow the Travis Build on 3.7 runs just fine?

Is there anything clearly wrong in the Dockerfile ?

Yay my docker image runs now!! There was some weirdness happening in codon translation so it's now its own method that gets tested separately for sanity.

Currently the build is failing due to integration and wheel building:

Thanks @olgabot, this is amazing! I'll cut a new release with all the merged PRs from this weekend.

Exciting! I'm also thinking about adding hydrohpobic-polar (HP) encoding which is even more lossy. --- Olga Botvinnik, PhD olgabotvinnik.com <http://www.olgabotvinnik.com>
