core.txt and mask.txt be available in ~/data.qiime_shellscripts) to the Desktop. qiime_tutorial on your Desktop. On Linux, you will need to substitute wget for curl (or install curl). As things progress, it is likely that you will have to edit the version number in the script. The zipped download remains on the Desktop, so if things get messed up, you won't have to repeat yourself. Then do:

I'll have to investigate how to do that. Perhaps if we follow the workflow script it will turn out correctly.

16S ribosomal RNA of rrnB operon
In agreement with other studies, [e.g. Katoh et al. (8)], we found that T-Coffee was unable to align more than approximately 102 sequences of typical length on a current desktop computer. CLUSTALW was able to align a few hundred sequences, with a practical limit around N = 103 where CPU time begins to scale approximately as N4. The largest set had 5000 sequences of average length 350. MUSCLE-p completed this test in 7 min, compared with 10 min for FFTNS1; we estimate that CLUSTALW would need approximately 1 year.
uclust. That's used both for MSA and at least one other step in the QIIME pipeline. I need to read the paper and we'll look at it another day.

These are in seqs_otus.txt identified by the names assigned in step 0.gg/core.txt (gg stands for Greengenes).aln/reps_aligned.txt. Here is the strangely sparse Greengenes type of alignment. You could use MUSCLE, but it takes a while.. Although for this relatively small example, it was just a few minutes.custom_parameters.txt as described in the tutorial. It provides options for all of the scripts in the sequence.

The QIIME install checks this variable and modifies its scripts (the she-bang thing), so I had to fix that later on.easy_install will fix you up quickly.muscle3.6_src around.

In .bash_profile:Sphinx installed (from the PyCogent instructions), so the documentation got built. But I've just been working from the web version anyway. On to the fun stuff.
nθ.I:
(u,v = v,u) does it take to put the numbers into ascending order? This sequence of three works:
x is cos(x) and for the cosine curve at x it is -sin(x).x, and then move a little bit h. Using the rule for sum of sines (here):-sin(x) times (1/h)(1 - cos(h)); last time we showed that (1/h)(1 - cos(h)) equals zero in the limit as h -> 0.cos(x) times (1/h) sin(h); we showed that (1/h) sin(h) approaches 1 as h -> 0. Thus, 
h is the measure of the angle and also the length of the arc of the circle between A and D (in radians). (I'm using h instead of x because ultimately this will be a small change to x, as in x + h).
OAB and OED are similar triangles so that ED/OD = AB/OB, and OD = 1. Thus, the inequality becomes:h = 0, we are allowed to divide by sin(h):h approaches 0, cos(h) and its inverse 1/cos(h) both approach 1 so the ratios h/sin(h) and sin(h)/h both approach 1 as well.sin(h) < h (see the figure again):h and also by 1 + cos(h):h -> 0 the right side must go to 0/2 (that is, 0) and our ratio is "caught in the middle."1-cos(h) and h are both approaching 0, h is approaching more slowly, so the ratio tends to the 0 in the limit. First the output:
y = a(x)2 translated to have a different vertex. I didn't do a systematic examination or anything, but here is one example in Python.quadratic takes arguments a, b, and c and returns the vertex (x0, y0) as well as a numpy array containing x such that |x - x0| <= 4, and a second one containing f(x) for each value of x.a = 1, 2 and 3. One set is at the origin (cyan, blue and purple). The second set (magenta, salmon and red) has c = 3 and:x0 = -b/2a is the same for each parabola in the second set, they all have the same axis of symmetry. The only difference (besides the shape parameter a) is y0, which can be calculated either from plugging a, b, c and x0 into the standard form, or by using the fact that
