## Plot a calogram

### Description

Plot a calodogram is based on EMBOSS command fdrawgram that is a wrapper command for command drawgram of the PHYLIP package.

This tool rooted phylogenies, cladograms, circular trees and phenograms in PostScript and PDF formats. Similar to DRAWTREE but plots rooted phylogenies.

### Parameters

- Iterate to improve tree (fdrawtree parameter -iterate: )
- Use branch lengths from user trees (fdrawtree parameter -lengths: )
- Label direction (fdrawtree parameter -labeldirection: )
- Angle the tree is to be plotted (fdrawtree parameter -treeangle: )
- Degrees the arc should occupy (fdrawtree parameter -arc: )
- Angle of labels (fdrawtree parameter -labelrotation: )
- Automatically rescale branch lengths (fdrawtree parameter -rescaled: )
- Centimeters per unit branch length (fdrawtree parameter -bscale: )
- Depth of tree as fraction of its breadth (fdrawtree parameter -treedepth: )
- Collect a log file

For more details, please check the manual page of fdrawgram command.

### Input and output

Input is a Phylip formatted tree file.

Output consists of two plot files containing the same tree. One in PDF and one in PostScript format.
