- reintegrates 'help' into 'trunk'
- tweak arb documentation:
- automatically link
- ticket references to arb
 tracker (only affects html version).
- found URLs.
- page titles
- warn about long titles.
- introduce SUBTITLEs (automatically triggered by multi-line titles in source files).
- increase allowed length (limited by subwindow width).
- cleanup header sections in all helpfiles.
- fix and/or update several help files.
- document syntax of help sources.
- build issues:
- when xml validation fails, next build no longer uses invalid xml ⇒ keeps failing.
- remove output files on error (including files below ARBHOME/lib).
- pipe output through logs to ensure proper wrapping in Entering/Leaving lines.
- moves Tree admin + NDS menu entries to top of menu
- adds: log:branches/help@18783:19531

| 3 | DESCRIPTION |
|---|
| 4 | |
|---|
| 5 | FastTree infers approximately-maximum-likelihood phylogenetic trees from |
|---|
| 6 | alignments of nucleotide or protein sequences. FastTree can handle alignments |
|---|
| 7 | with up to a million of sequences in a reasonable amount of time and memory. |
|---|
| 8 | For large alignments, FastTree is 100-1,000 times faster than PhyML 3.0 or RAxML 7. |
|---|
| 9 | |
|---|
| 10 | FastTree is more accurate than PhyML 3 with default settings, and much more accurate |
|---|
| 11 | than the distance-matrix methods that are traditionally used for large alignments. |
|---|
| 12 | FastTree uses the Jukes-Cantor or generalized time-reversible (GTR) models of |
|---|
| 13 | nucleotide evolution and the JTT (Jones-Taylor-Thornton 1992), WAG (Whelan & Goldman 2001), |
|---|
| 14 | or LG (Le and Gascuel 2008) models of amino acid evolution. |
|---|
| 15 | To account for the varying rates of evolution across sites, |
|---|
| 16 | FastTree uses a single rate for each site (the "CAT" approximation). |
|---|
| 17 | To quickly estimate the reliability of each split in the tree, FastTree computes |
|---|
| 18 | local support values with the Shimodaira-Hasegawa test (these are the |
|---|
| 19 | same as PhyML 3's "SH-like local supports"). |
