evalue selection slider

[yeban]

I guess the title says it all.

Found this one on the Todo wiki page (which I am cleaning up, and intend to remove soon).

Thanks yeb. Good call removing the redundancy.

This will take good amount of time. Any hints on how to go about it?

[yannickwurm]

really?

Something like this: http://chromeadblock.com/donate/

but just with three stringency settings.... which use JS to simply reset/repopulate the advanced-params textfield

What shall we say are the stringency settings? Just a simple e-value thing, with 1e-5, 1e-20, 1e-40 ? Or do we include % identities in it as well? I would think just straight e-values should do it, to keep it simple?

That slider doesn't work for me by the way.

Not sure what the best "stringent" and best "lenient" settings are.

• BLOSUM matrix can be changed too.
• Word size can be increased/decreased (which makes things faster/slower).
• Gap opening/extension penalties (but I'm not very familiar with those).

Well, I was thinking of dynamically filtering queries based on evalue. I talked about it when you gave me a quick intro to BLAST, remember?

Simply tweaking advanced params shouldn't take much time except to figure out how and where to place the slider :P.

Ok. Sorry I was thinking about #48.

I think #48 is easier to implement. (And more useful?)

Well, this one was marked 'priority' and there are so many issues that I failed to noticed #48 :|.

Yup, that should be easier. Ben and you should be able to advise better on which one would be more useful. In any case, if evalue slider is a 'priority', we should go ahead with #48 now and experiment with dynamically filtering search results based on evalue later.
