Function Draw a helical net for a protein sequence Description pepnet draws a helical net for an input protein sequence. This is a method of displaying the residues of a protein in a simple 3,4,3,4 repeating pattern that emulates at a simple level the arrangement of residues around an alpha helix. It is therefore easy to see patterns of amphipathicity that you may wish to investigate in more detail by using displays such as pepwheel. You can specify which residues to mark up in squares, diamonds and octagons. Usage Here is a sample session with pepnet % pepnet -sask Draw a helical net for a protein sequence Input protein sequence: tsw:gcn4_yeast Begin at position [start]: 253 End at position [end]: 274 Graph type [x11]: cps Created pepnet.ps Go to the input files for this example Go to the output files for this example Command line arguments Draw a helical net for a protein sequence Version: EMBOSS:6.4.0.0 Standard (Mandatory) qualifiers: [-sequence] sequence Protein sequence filename and optional format, or reference (input USA) -graph graph [$EMBOSS_GRAPHICS value, or x11] Graph type (ps, hpgl, hp7470, hp7580, meta, cps, x11, tek, tekt, none, data, xterm, png, gif, pdf, svg) Additional (Optional) qualifiers (* if not always prompted): * -squares string [ILVM] By default the aliphatic residues ILVM are marked with squares. (Any string) * -diamonds string [DENQST] By default the residues DENQST are marked with diamonds. (Any string) * -octags string [HKR] By default the positively charged residues HKR are marked with octagons. (Any string) Advanced (Unprompted) qualifiers: -amphipathic toggle If this is true then the residues ACFGILMVWY are marked as squares and all other residues are unmarked. This overrides any other markup that you may have specified using the qualifiers '-squares', '-diamonds' and '-octags'. Associated qualifiers: "-sequence" associated qualifiers -sbegin1 integer Start of the sequence to be used -send1 integer End of the sequence to be used -sreverse1 boolean Reverse (if DNA) -sask1 boolean Ask for begin/end/reverse -snucleotide1 boolean Sequence is nucleotide -sprotein1 boolean Sequence is protein -slower1 boolean Make lower case -supper1 boolean Make upper case -sformat1 string Input sequence format -sdbname1 string Database name -sid1 string Entryname -ufo1 string UFO features -fformat1 string Features format -fopenfile1 string Features file name "-graph" associated qualifiers -gprompt boolean Graph prompting -gdesc string Graph description -gtitle string Graph title -gsubtitle string Graph subtitle -gxtitle string Graph x axis title -gytitle string Graph y axis title -goutfile string Output file for non interactive displays -gdirectory string Output directory General qualifiers: -auto boolean Turn off prompts -stdout boolean Write first file to standard output -filter boolean Read first file from standard input, write first file to standard output -options boolean Prompt for standard and additional values -debug boolean Write debug output to program.dbg -verbose boolean Report some/full command line options -help boolean Report command line options and exit. More information on associated and general qualifiers can be found with -help -verbose -warning boolean Report warnings -error boolean Report errors -fatal boolean Report fatal errors -die boolean Report dying program messages -version boolean Report version number and exit Input file format pepnet reads a single protein sequence. 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. See: http://emboss.sf.net/docs/themes/SequenceFormats.html for further information on sequence formats.
