We run into a similar problem as we have right now, and why our current
method is static.  We have 5 different strains in which we need to convert
over into usable data.  Each strain has different set of data, some similar,
some not.  We're looking specifically for the mutations, but also for
markers of where the strain is found against our base comparison strain.

Currently, running out system as it is, the time it takes to generate the
output, is quite long, see:
http://clab.ist.unomaha.edu/CLAB/index.php/Talk:RT386#Profiling

The first test, is with a speed hack we had, that only loaded 1 strain of
data into the mixer, and generated only a snipplet of the genetic code, that
we could use for comparison of the design of the current output.  EG to give
us the best results, without running the same generation over and over and
over again, awaiting the length that the second part gives us.  Which, you
can see from the second set of test results, how long it takes to render 5
strains of data, into usable HTML format.

Also, as a side note, I sent this in a previous email, but was not
subscribed to the PM Email list, so I'm re-posting it here, to save space.

SVG would never, ever hold up to the rendering of the millions of base pairs
that are generated from the blast output.  I've looked at that as a
possibility for graphical representation, and just the shear amount of
generated data from both blast, and our own HTML output is demonstrated
below:

blast_output size: 38m (All 5 strains blasted)
html size: 15 megs (give or take a few kilobytes for svn repo data, and
images used in my tool you listed below)

SVG would have a literal field day trying to load that much data up in the
scalable method, to zoom into the individual amplicons of the DNA Strand,
not counting all 5 that we are looking at.
