Feature request - Custom bead channel selection

[mleipold]

It would be nice if there were an option to select Custom channels for beads. This was a feature in the original Finck MATLAB normalizer ("Custom").

This would help address any future Norm bead developments before they got added to the default dropdowns (like how it was a few weeks before XT beads got added), and would also help cases where a bead channel got left out of a panel (and therefore FCS file) by mistake.

See here for one example: http://cytoforum.stanford.edu/viewtopic.php?f=4&t=3705&p=7957
