Clicking on the figures you will visualize the original PostScript file. 
Clicking on the book you will visualize the original GFF file. 
Clicking on the green loop you will visualize the configuration file. 
Clicking on the stars you also can download a tarball for each figure, containing the PostScript file, a brief report on how it was obtained and the configuration file used (if any).

GFF2PS makes many assumptions on how things have to be displayed. To illustrate this, the plot on the left was generated without any configuration file, only few command-line options, one of which forced two pages output, another one changed page size to "A5" format and the last defining a new title string. Command-line was: gff2ps -s a5 -P 2 -T "Default.ps" < GFF_sample.gff > Default.psAt top of the figures there is the header area, and from top to bottom, forward strand sources, the middle area for those features without defined strand, and reverse strand sources. Ordering for sources is taken from input files and is preserved on forward section but inverted on reverse section. In the middle area two scoring vectors are shown as color gradients. The next three examples share the same GFF input file with current plot. |

Here we have set a user-defined page size (10.5x42cm) and many variables in the custom file 1bx1p_long.rc.Only forward strand (upper half) and reverse strand (lower half) are represented, and are splited by the scale rule. The track labeled with "ANNOT" has been resized and shows all the features start-end positions. |

Default page size is "A4", like in this plot. We have switched off the reverse strand and the no-strand areas, so it's displayed only forward strand features. You can see different shapes that were assigned in the custom file to the features in the input GFF-file. You can also see how the program splits (by default) source tracks when there are overlapping groups within a given source (EXP and SCAN tracks). |

In this example we have forced not to split source tracks when overlapping groups were reported (see EXP and SCAN tracks and compare them with the previous figure). We have changed many feature colors, the color gradient for G+C tracks too. You can easily set up to 67 pre-defined colors for almost all plot attributes. |

In this example we have defined one shape for each feature in the GFF-file, three different lines for the groups, and the four different vertical alignments for source tracks in forward strand (upper half) and reverse strand (lower half). In the configuration file we have used regular expressions to set group labels and group lines, and a feature_color variable definition at source section to force all features in every source to be filled with the same color. |
