Idiogram Plotter

Visualise copy-number changes on a human chromosome idiogram (hg38)
Input A — simplified karyotype string, e.g. 46,XY,-2(s),+X
Input B — segment coordinates with type, e.g. chr16:27575535:77197873:49.6 MB:High mosaic loss
Karyotype is not sanity-checked.

Format: 46,XY[,±chrom(modifiers)…] | Modifiers: s=segmental m=low mosaic M=high mosaic

B — Segment coordinates

Format: chr:start:end:size:type[:cn:conf:annot] | multiple regions separated by ;
