question about Challenge 7 data

[Qiu,Peng]

Hi there,

 

I have a question about the data for challenge 7.

 

In each of the 7 FCS files in this challenge, the total number of markers/channels is 38. Except for FSC and SSC, all other channels appear to be duplicated, according to the name of each channel.

 

I also looked at the data in one of the 7 FCS files. It appears that if two channels share the same name, the raw data for the two channels are highly correlated but not identical.

 

Could you please clarify what is the meaning of the channels?

 

Thanks a lot.
