パッケージ: gff2aplot (2.0-14)

pair-wise alignment-plots for genomic sequences in PostScript

A program to visualize the alignment of two genomic sequences together with their annotations. From GFF-format input files it produces PostScript figures for that alignment. The following menu lists many features of gff2aplot:

 * Comprehensive alignment plots for any GFF-feature. Attributes are defined
   separately so you can modify only whatsoever attributes for a given file or
   share same customization across different data-sets.
 * All parameters are set by default within the program, but it can be also
   fully configured via gff2ps-like flexible customization files. Program can
   handle several of such files, summarizing all the settings before producing
   the corresponding figure. Moreover, all customization parameters can be set
   via command-line switches, which allows users to play with those parameters
   before adding any to a customization file.
 * Source order is taken from input files, if you swap file order you can
   visualize alignment and its annotation with the new input arrangement.
 * All alignment scores can be visualized in a PiP box below gff2aplot area,
   using grey-color scale, user-defined color scale or score-dependent
   gradients.
 * Scalable fonts, which can also be chosen among the basic PostScript default
   fonts. Feature and group labels can be rotated to improve readability in
   both annotation axes.
 * The program is still defined as a Unix filter so it can handle data from
   files, redirections and pipes, writing output to standard-output and
   warnings to standard error.
 * gff2aplot is able to manage many physical page formats (from A0 to A10, and
   more -see available page sizes in its manual-), including user-defined ones.
   This allows, for instance, the generation of poster size genomic maps, or
   the use of a continuous-paper supporting plotting device, either in portrait
   or landscape.
 * You can draw different alignments on same alignment plot and distinguish
   them by using different colors for each.
 * Shape dictionary has been expanded, so that further feature shapes are now
   available (see manual).
 * Annotation projections through alignment plots (so called ribbons) emulate
   transparencies via complementary color fill patterns. This feature allows
   one to show color pseudo-blending when horizontal and vertical ribbons
   overlap.
