+ + By default the transcript isoform with the highest coverage is drawn. + Alternatively, the transcript isoform that is provided in the columns + transcript_id1 and transcript_id2 in the given fusions file can be drawn. + Selecting the isoform with the highest coverage usually produces nicer plots, + in the sense that the coverage track is smooth and shows a visible increase in coverage after the fusion breakpoint. + However, the isoform with the highest coverage may not be the one that is involved in the fusion. + Often, genomic rearrangements lead to non-canonical isoforms being transcribed. + For this reason, it can make sense to rely on the transcript selection provided by the columns transcript_id1/2, + which reflect the actual isoforms involved in a fusion. +\ As a third option, the transcripts that are annotated as canonical can be drawn. + Transcript isoforms tagged with appris_principal, appris_candidate, or CCDS are considered canonical. + + + + + + + The fusion of interest is drawn as a solid line in the circos plot. + To give an impression of the overall degree of rearrangement, + all other fusions are drawn as semi-transparent lines in the background. + This option determines which other fusions should be included in the circos plot. + Values specify the minimum confidence a fusion must have to be included. + It usually makes no sense to include low-confidence fusions in circos plots, + because they are abundant and unreliable, and would clutter up the circos plot. + Default: medium + + + + + + + + This option only applies to intergenic breakpoints. + If it is set to a value greater than 0, then the script draws the genes + which are no more than the given distance away from an intergenic breakpoint. + Note that this option is incompatible with squishIntrons. + Default: 0 + + + + Exons usually make up only a small fraction of a gene. + They may be hard to see in the plot. i + Since introns are in most situations of no interest in the context of gene fusions, + this switch can be used to shrink the size of introns to a fixed, negligible size. + It makes sense to disable this feature, if breakpoints in introns are of importance. + Default: TRUE + + + + + + + Occasionally, domains are annotated redundantly. + For example, tyrosine kinase domains are frequently annotated as + Protein tyrosine kinase and Protein kinase domain. + In order to simplify the visualization, such domains can be merged into one, + given that they overlap by the given fraction. + The description of the larger domain is used. + Default: 0.9 + + + + By default the number of an exon is printed inside each exon, + which is taken from the attribute exon_number of the GTF annotation. + When a gene has many exons, the boxes may be too narrow to contain the labels, + resulting in unreadable exon labels.
