pipeline ideogram question #651

Closed wcmcintosh closed 9 years ago

When one right-clicks and chooses to export a CSV file, what value is being saved in the Y0 column?

jirhiker commented 9 years ago

the relative probability. Y0 is the current relative probability (i.e solid curve) and Y1 is the original relative probability (i.e dashed curve)

wcmcintosh commented 9 years ago

That seems sensible, but for some reason there are integers or negative numbers among the YO values in some cases.

Here are values for 24162 and 24163, no excluded points 28.08338882 1 28.14396726 2 28.15518491 3 28.18078664 4 28.19774496 5 28.19969472 6 28.21283551 7 28.26345718 8 28.27427649 9 28.28732407 10 28.2926094 11 28.30420488 12
