When I try to open some FCS files using iFlow, I get several strange
error messages, and I am ultimately unable to open the files.... In
iFlow, I get a pop-up box that says "Warning: 'signed = FALSE' is
only valid for integers of sizes 1 and 2." In the R console, there are
some warnings about RGtk2 'method' being deprecated - how can I clear
this?
When I try to open the FCS file directly in R using the underlying
flowCore function read.FCS, I receive the same type of error message
as from the iFlow GUI, but the file reads in properly into R. Why is
the error message appearing, and why doesn't iFlow allow me to do the
same thing, instead refusing to parse the file?
[The FCS files are version 3.0 generated by FACSDiva 6.1.3; samples
were acquired on a BD LSR II flow cytometer.]
I copy the R console output below with session information at the end.
