Unfortunally it is in Portuguese Dissertation
The tool's output files have different extensions, and can be used in
conjunction with the genome visualization tool Artemis (CARVER et al.,
2012) for a better understanding of the results. The first in .TXT, it
has information of all the atypical regions, with their initial
position and endpoint in the genome of each candidate GIs, along with
their IVOM score and Threshold, in addition to informing the color of
the corresponding Features for visualization in the Artemis external
tool. The second .PLOT extension is a plotting file graph
corresponding to the atypical regions in the genome that the tool
detected, can be inserted as an input file in the Artemis software.
@Ram Thanks for help to clean up the post.
