Function Calculate fractional GC content of nucleic acid sequences Description geecee calculates the fraction of G+C bases of the input nucleic acid sequence(s). It sums the number of G and C bases in the input sequence(s) and writes the result to file as the fraction (in the interval 0.0 to 1.0) of the length of the whole sequence. Usage Here is a sample session with geecee % geecee tembl:L46634 Calculate fractional GC content of nucleic acid sequences Output file [l46634.geecee]: Go to the input files for this example Go to the output files for this example Command line arguments Calculate fractional GC content of nucleic acid sequences Version: EMBOSS:6.4.0.0 Standard (Mandatory) qualifiers: [-sequence] seqall Nucleotide sequence(s) filename and optional format, or reference (input USA) [-outfile] outfile [*.geecee] Output file name Additional (Optional) qualifiers: (none) Advanced (Unprompted) qualifiers: (none) Associated qualifiers: "-sequence" associated qualifiers -sbegin1 integer Start of each sequence to be used -send1 integer End of each 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 "-outfile" associated qualifiers -odirectory2 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 geecee reads one or more nucleotide sequences. 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. Input files for usage example 'tembl:L46634' is a sequence entry in the example nucleic acid database 'tembl' Database entry: tembl:L46634 ID L46634; SV 1; linear; genomic DNA; STD; VRL; 1272 BP.
