Hi,

I'm using cellHTS2 for a large siRNA screening project and want to rename the channels. The cellHTS instance I created has the default names:

> channelNames(x)
[1] "Channel 1" "Channel 2" "Channel 3" "Channel 4" "Channel 5" "Channel 6"
[7] "Channel 7" "Channel 8"

The documentation in version 2.22.0 of Package 'cellHTS2' is: 

channelNames<-(object, value)
signature(object = "cellHTS", value = "character"). Replace the channel names in object.

The way I interpret this, I think the following code should work:

#create new names for the channels
chnames=c('All#','G1/S','G2','M','Aneuploid','Apoptotic','cPARP','Envision')

#Assign the new names to the channels
channelNames(x,chnames)

The result is:

Error in .local(object, ...) : 
  unused argument (c("All#", "G1/S", "G2", "M", "Aneuploid", "Apoptotic", "cPARP", "Envision"))

Can you please explain the proper way to change the channel names?


thank you for your help,
