# graphlan(1)

circular representations of taxonomic and phylogenetic trees

## NAME

graphlan - circular representations of taxonomic and phylogenetic trees

## SYNOPSIS

**graphlan** \[-h\] \[--format \['output\_image\_format'\]\] \[--warnings WARNINGS\] \[--positions POSITIONS\] \[--dpi image\_dpi\] \[--size image\_size\] \[--pad pad\_in\] \[--external\_legends\] \[-v\] input\_tree output\_image

## DESCRIPTION

GraPhlAn is a software tool for producing high-quality circular representations of taxonomic and phylogenetic trees. It focuses on concise, integrative, informative, and publication-ready representations of phylogenetically- and taxonomically-driven investigation.

## OPTIONS

### positional arguments:

- input\_tree

  the input tree in PhyloXML format

- output\_image

  the output image, the format is guessed from the extension unless **--format** is given. Available file formats are: png, pdf, ps, eps, svg

### optional arguments:

- **-h**, **--help**

  show this help message and exit

- **--format** \['output\_image\_format'\]

  set the format of the output image (default none meaning that the format is guessed from the output file extension)

- **--warnings** WARNINGS

  set whether warning messages should be reported or not (default 1)

- **--positions** POSITIONS

  set whether the absolute position of the points should be reported on the standard output. The two cohordinates are r and theta

- **--dpi** image\_dpi

  the dpi of the output image for non vectorial formats

- **--size** image\_size

  the size of the output image (in inches, default 7.0)

- **--pad** pad\_in

  the distance between the most external graphical element and the border of the image

- **--external\_legends**

  specify whether the two external legends should be put in separate file or keep them along with the image (default behavior)

- **-v**, **--version**

  Prints the current GraPhlAn version and exit
