[BioC] Flow Cytometry Analysis with FlowCore

[Telma Fernandes [guest]]

I wanna know how to do transformation of the channel four (FLH 4) without using the standard transformations offer by the flowCore package?

The values of the channel four are between 1 and 4096 and i need to convert in values between 1 and 246 with the rule 10^(x/1024).

Thank you.
