prettyplot

 

Function

Draw a sequence alignment with pretty formatting

Description

prettyplot draws a plot of the input sequence alignment. The sequences are rendered in pretty formatting on the specified graphics device. Drawing options control the appearance of the image, such as boxes, colour and shading for highlighting conserved regions.

Data files

Prettyplot uses a comparison matrix file to calculate similarity to the consensus.

For protein sequences EBLOSUM62 is used for the substitution matrix. For nucleotide sequence, EDNAFULL is used.

EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by the EMBOSS environment variable EMBOSS_DATA.

To see the available EMBOSS data files, run:

% embossdata -showall

To fetch one of the data files (for example 'Exxx.dat') into your current directory for you to inspect or modify, run:


% embossdata -fetch -file Exxx.dat

Users can provide their own data files in their own directories. Project specific files can be put in the current directory, or for tidier directory listings in a subdirectory called ".embossdata". Files for all EMBOSS runs can be put in the user's home directory, or again in a subdirectory called ".embossdata".

The directories are searched in the following order:

Notes

A consesnsus sequence is calculated for the alignment and individual sequences compared to the consensus using the specified comparison matrix file. The default matrix for protein sequences is EBLOSUM62 and for nucleotide sequences is EDNAFULL. The drawing options render conserved sites and regions identified from the comparisons. For example, residues in a sequence are classed as "identical", "similar" or "other" to the consensus depending on user-specified thresholds of sequence similarity (-pair option). Residues in each class are rendered red, green and black by default (this can be changed).

There are other more general drawing options, for example, controlling the number of residues displayed per line, background shading and whether to display sequence names or not.

Many features were first implemented in the EGCG program "prettyplot" by Peter Rice (pmr © ebi.ac.uk)
Informatics Division, European Bioinformatics Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SD, UK

The original suggestions for the PrettyPlot program were from Denis Duboule and Sigfried Labeit at EMBL. Gert Vriend added the star marking. Rita Grandori suggested the -NOCOLLISION option.
