# AB12PHYLO
[AB12PHYLO](https://github.com/lkndl/ab12phylo) is an integrated, easy-to-use pipeline for Maximum Likelihood (ML) phylogenetic tree inference from ABI traces and `FASTA` data.
At its core, AB12PHYLO runs parallelized instances of [RAxML-NG](https://github.com/amkozlov/raxml-ng) (Kozlov et al. 2019) or [IQ-Tree](https://github.com/iqtree/iqtree2) (Nguyen et al. 2015) as well as a BLAST search in a reference database.
It enables visual, effortless sample identification based on phylogenetic position and sequence similarity, as well as population subset selection aided by metrics like Tajima's D for estimations of ongoing evolution, or definition of haplotypes.
## Documentation
There are two versions of AB12PHYLO, both started from a terminal: `ab12phylo` as a graphical user interface intended to be more user-friendly and intuitive, and in some details more powerful than `ab12phylo-cmd`. This version, on the other hand, is a commandline-only tool for maximum reproducibility and automation of a linear pipeline.
While `ab12phylo` comes with its own on-screen help, and a very brief example for `ab12phylo-cmd` is provided below, detailed installation and usage instructions can be found in the [github wiki](https://github.com/lkndl/ab12phylo/wiki). Especially for the commandline `ab12phylo-cmd`, also check the in-line help via `ab12phylo-cmd -h`.
For more individual support or feature requests, please write an email to [ab12phylo@gmail.com](mailto:ab12phylo@gmail.com).
## Installation
AB12PHYLO can be installed using conda or pip:
```shell script
conda install -c lkndl -c conda-forge -c bioconda ab12phylo
```
or
```shell script
pip install ab12phylo
```
| :memo: | WINDOWS USERS |
|--------|:--------------|
*Windows users **must** use Anaconda, and run `ab12phylo-init` before starting the graphical `ab12phylo`!*
When AB12PHYLO is first run, it will check the system for three important non-python tools: RAxML-NG, IQ-Tree 2 and BLAST+. If they are not installed or outdated, AB12PHYLO can download the latest static binaries from GitHub or the NCBI respectively. Check the [wiki](https://github.com/lkndl/ab12phylo/wiki/Installation) for more details, troubleshooting, installing from source or updating the package.
As implied above, start the graphical version via `ab12phylo` from the terminal, and invoke the commandline version via `ab12phylo-cmd`.
## Quick start and functionality
ABI trace files are the main input for AB12PHYLO. Additionally, wellsplate tables can be used to translate back to original sample IDs, provided the mapping is identical for all sequenced genes. Reference data may be included in `FASTA` format, and the graphical AB12PHYLO accepts `FASTA` sequences as the main input format as well.
**A:**
Sequence data is extracted from ABI trace files using a customisable quality control: Sequence ends are trimmed with a sliding window until a certain number (*8 out of 10 by default*) of bases reach the minimal accepted phred quality score (*between 0 and 60, 30 by default*). Bases with low phred quality are replaced by `N` only if they form a consecutive stretch that is longer than a certain threshold (*5 by default*).
**B:**
Samples missing for a single locus are discarded for all genes. Trimmed traces as well as reference and `FASTA` sequences are aligned into single-gene Multiple Sequence Alignments (MSAs), which are then each trimmed to a user-defined level conserved positions using Gblocks 0.91b. For multi-gene analyses, the single-gene MSAs are then concatenated into a multi-gene MSA, which is used for ML tree inference. Trees are re-constructed using either RAxML-NG or IQ-Tree 2, with only the latter one available for Windows.
**C:**
AB12PHYLO allows editing of the resulting tree and selection of taxa by label matching, shared ancestry or manual picking. For these selected sub-populations, basic population genetics neutrality and diversity metrics are calculated from the conserved MSA positions only, with adjustable tolerance of gaps and unknown characters. The graphical `ab12phylo` is both less cumbersome and more capable for these applications; the wiki pages ([`ab12phylo`](https://github.com/lkndl/ab12phylo/wiki/Graphical-interface), [`ab12phylo-cmd`](https://github.com/lkndl/ab12phylo/wiki/Commandline-version#results--motif-search)) have more details.
A BLAST search for species annotation can be run on a local database, or via the public NCBI BLAST API. However, importing XML results of a [web BLAST](https://blast.ncbi.nlm.nih.gov/Blast.cgi) should be preferred to running remote API calls as a main strategy.
## A simple `ab12phylo-cmd` example
A simple real-world invocation of commandline AB12PHYLO might look like this:
```shell script
ab12phylo-cmd -abi <seq_dir> \
-csv <wellsplates_dir> \
-g <barcode_gene> \
-rf <ref.fasta> \
-bst 1000 \
-dir <results>
```
where:
* `<seq_dir>` contains all input ABI trace files, ending in `.ab1`
* `<wellsplates_dir>` contains the `.csv` mappings of user-defined IDs to sequencer's isolate coordinates
* `<barcode_gene>` was sequenced, see [here](https://github.com/lkndl/ab12phylo/wiki/Commandline-version#genes-and-references) for more info
* `<ref.fasta>` contains full GenBank reference records [like this](https://www.ncbi.nlm.nih.gov/nuccore/AF347033.1?report=fasta&log$=seqview&format=text)
* 1000 `-bst` = `--bootstrap` trees will be generated
* `<results>` is where results will be
