optional arguments:¶

-h, --help

show this help message and exit

-v, --version

show program's version number and exit

DECOMPOSITION OPTIONS:¶

These options determine the alignment decomposition size and taxon insertion size. If None is given, then the default is to align/place at 10% of total taxa. The alignment decomosition size must be less than the taxon insertion size.

-A N, --alignmentSize N

max alignment subset size of N [default: 10% of the total number of taxa or the placement subset size if given]

-P N, --placementSize N

max placement subset size of N [default: 10% of the total number of taxa or the alignment length (whichever bigger)]

-F N, --fragmentChunkSize N

maximum fragment chunk size of N. Helps controlling memory. [default: 20000]

-D DISTANCE, --distance DISTANCE

minimum p-distance before stopping the decomposition[default: 1]

-M DIAMETER, --diameter DIAMETER

maximum tree diameter before stopping the decomposition[default: None]

-S DECOMP, --decomp_strategy DECOMP

decomposition strategy [default: using tree branch length]

OUTPUT OPTIONS:¶

These options control output.

-p DIR, --tempdir DIR

Tempfile files will be written to DIR. Full-path required. [default: /tmp/sepp]

-rt, --remtemp

Remove tempfile directory. [default: disabled]

-o OUTPUT, --output OUTPUT

output files with prefix OUTPUT. [default: output]

-d OUTPUT_DIR, --outdir OUTPUT_DIR

output to OUTPUT_DIR directory. full-path required. [default: .]

INPUT OPTIONS:¶

These options control input. To run SEPP the following is required. A backbone tree (in newick format), a RAxML_info file (this is the file generated by RAxML during estimation of the backbone tree. Pplacer uses this info file to set model parameters), a backbone alignment file (in fasta format), and a fasta file including fragments. The input sequences are assumed to be DNA unless specified otherwise.

-c CONFIG, --config CONFIG

A config file, including options used to run SEPP. Options provided as command line arguments override config file values for those options. [default: None]

-t TREE, --tree TREE

Input tree file (newick format) [default: None]

-r RAXML, --raxml RAXML

RAxML_info file including model parameters, generated by RAxML.[default: None]

-a ALIGN, --alignment ALIGN

Aligned fasta file [default: None]

-f FRAG, --fragment FRAG

fragment file [default: None]

-m MOLECULE, --molecule MOLECULE

Molecule type of sequences. Can be amino, dna, or rna [default: dna]

--ignore-overlap

When a query sequence has the same name as a backbone sequence, ignore the query sequences and keep the backbone sequence[default: False]

OTHER OPTIONS:¶

These options control how SEPP is run

-x N, --cpu N

Use N cpus [default: number of cpus available on the machine]

-cp CHCK_FILE, --checkpoint CHCK_FILE

checkpoint file [default: no checkpointing]

-cpi N, --interval N

Interval (in seconds) between checkpoint writes. Has effect only with -cp provided. [default: 3600]

-seed N, --randomseed N

random seed number. [default: 297834]
