All methods related to Enterobase data analysis pipelines.
EToKi was developed and tested in both Python 2.7 and Python 3.5. EToKi depends on several Python libraries:
ete3
numba
numpy
pandas
psutil
sklearn
All libraries can be installed using pip:
pip install ete3 numba numpy pandas sklearn psutil
EToKi also calls the following 3rd party programs for different pipelines:
raxml
fasttree
rapidnj
bbmap
mmseqs
ncbi-blast
usearch
spades
megahit
samtools
pilon
gatk
bwa
bowtie2
minimap2
kraken2 & minikraken2
lastal & lastdb
pilercr
trf
All 3rd party programs except for usearch can be automatically installed using configure command:
python EToKi.py configure --install --download_krakenDB
NOTE: This has only been tested in Ubutu 16.06 but is expected to run on other 64-bit Linux systems.
Usearch is a commercial program and allows free use of the 32-bit version for individuals. Please download it from https://www.drive5.com/usearch/
After it is downloaded, pass its executable file to EToKi using --usearch
python EToKi.py configure --usearch /path/to/usearch
You can also run both --install and --usearch at the same time:
python EToKi.py configure --install --download_krakenDB --usearch /path/to/usearch
Note that --download_krakenDB will download the minikraken2 database, which is about 8GB in size. Alternatively, you can use --link_krakenDB to pass a different Kraken database to EToKi.
python EToKi.py configure --install --link_krakenDB /path/to/krakenDB --usearch /path/to/usearch
You can also use pre-installed 3rd party programs in EToKi, by passing their absolute paths into the program using --path. This argument can be specified multiple times in the same command:
python EToKi.py configure --path fasttree=/path/to/fasttree --path raxml=/path/to/raxml

EToKi assemble is a joint method for both de novo assembly and reference-guided assembly.
-
de novo assembly approach calls either SPAdes (default) or MEGAHIT (default for metagenomic data) on short reads that have been cleaned up using EToKi prepare, and uses Pilon to polish the assembled scaffolds and evaluate the reliability of consensus bases of the scaffolds.
-
Reference-guided assembly is also called "reference mapping". Short reads are aligned to a user-specified reference genome using minimap2. Nucleotide bases of the reference genome are updated using Pilon, according to the consensus base calls of the covered reads. Non-specific metagenomic reads of closely related species can sometimes also align to the reference genome and confuse consensus calling. Two arguments, --outgroup and --ingroup, are given to pre-filter these non-specific reads and obtain clean SNP calls.
