pepinfo |
Please help by correcting and extending the Wiki pages.
pepinfo plots various amino acid properties in parallel for an input protein sequence. The types of plot available are i. Hydrophobicity plots using the method of Kyte & Doolittle, the optimal matching hydrophobicity scale (OHM) of Sweet & Eisenberg, or consensus parameters (Eisenberg et al). ii. Histogram of the presence of residues with the physico-chemical properties: Tiny, Small, Aliphatic, Aromatic, Non-polar, Polar, Charged, Positive, Negative. The data are also written out to an output file.

The input is a standard EMBOSS sequence query (also known as a 'USA').
Major sequence database sources defined as standard in EMBOSS installations include srs:embl, srs:uniprot and ensembl
Data can also be read from sequence output in any supported format written by an EMBOSS or third-party application.
The input format can be specified by using the command-line qualifier -sformat xxx, where 'xxx' is replaced by the name of the required format. The available format names are: gff (gff3), gff2, embl (em), genbank (gb, refseq), ddbj, refseqp, pir (nbrf), swissprot (swiss, sw), dasgff and debug.

The output is to the specified graphics device.
The results can be output in one of several formats by using the command-line qualifier -graph xxx, where 'xxx' is replaced by the name of the required device. Support depends on the availability of third-party software packages.
The device names that output to a file are: ps (postscript), cps (colourps), png, gif, pdf, svg, hpgl, hp7470, hp7580, das, data.
The other available device names are: meta, x11 (xwindows), tek (tek4107t), tekt (tektronix), xterm, text.
Output can be turned off by specifying none (null).
See: http://emboss.sf.net/docs/themes/GraphicsDevices.html for further information on supported devices.

![[pepinfo results]](pepinfo.1.pepinfo.gif)
The output file 'pepinfo.out' contains the coordinates from the graphs.
For the first set of graphs, 9 sets of true/false values are written out. For the second set of graphs, 3 sets of hydrophobicity values are written.
The hydropathy data of the residues are read from the EMBOSS data file 'Eaa_hydropathy.dat'. This file can be copied into your current directory and inspected ot altered by using the application 'embossdata -fetch'. Another file can be specified using the qualifier '-aahydropathy'.
EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by EMBOSS environment variable EMBOSS_DATA.
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:
For calculating the hydrophobicity plots, hdrophobicity is calculated in windows of a specified size over the sequence.
The optimal matching hydrophobicity scale (OHM) scale is based on the likelihood of a given amino acid to be replaced by another hydrophobic or "buried" amino acid.
