This output is not described in any of the documentation, though it is displayed on the documentation page. It would be useful to have what these codes mean on the documentation page and what each means.
if(alignedConcordant()) {
o.append("CP");
} else if(alignedDiscordant()) {
o.append("DP");
} else if(alignedUnpairedMate()) {
o.append("UP");
} else if(alignedUnpaired()) {
o.append("UU");
}
Thank you! I added documentation for this to the manual. The new manual text (also below) will be present in the next release.
Best,
Ben
